[0002] In the construction operation of a group of hollow box-shaped dense single crystal furnace bases, templates need to be erected on the four side walls of each single crystal furnace base, so that a concrete pouring area is formed between the inner and outer templates of the single crystal furnace base. In the actual construction operation process, the engineering quantities involved in the transportation, erection, fixing and demolition operations of the templates are extremely large. For example, in the process of template erection, it involves the transportation, erection and fixing of templates. In the prior art, relying on construction workers to adopt the operation mode of erecting templates one by one in the order of constructing single crystal furnace bases one by one, the construction operation process is extremely complex, time-consuming and laborious, resulting in a very long construction period for the template erection process in the entire construction period of the single crystal furnace base construction operation. Moreover, there are a large number of repetitive construction operation processes. In view of this, the present application provides an erection device for a group of hollow box-shaped dense single crystal furnace basic templates. Summary of the Invention

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] As Figures 1 to 16 shown, a hollow box-shaped dense single crystal furnace foundation group template erection device provided by the present invention includes:

[0047] A walking frame 1, which is used to support the overall displacement of the device on the ground.

[0048] A first cross hanger 2, which is suspended inside the walking frame 1 in a liftable manner;

[0049] A second cross hanger 3, which is suspended on the first cross hanger 2 in a liftable manner;

[0050] The template placement rack 4 is provided at each of the four ends of the first cross hanger 2. The four template placement racks 4 are respectively arranged corresponding to the four side walls of the single crystal furnace foundation. The inner and outer sides of the template placement rack 4 are the template outlet and the template inlet respectively. The templates are placed upright and side by side in the template placement rack 4;

[0051] The template lowering rack 5 is provided at each of the four ends of the second cross hanger 3. The four template lowering racks 5 are respectively arranged corresponding to the four template outlets;

[0052] The bottom upper supporting plate 6 is arranged below the template outlet. The bottom upper supporting plate 6 is installed on the template placement rack 4 and is used to support the template located in the template outlet from the bottom;

[0053] The top upper supporting plate 7 is arranged above the template outlet. The top upper supporting plate 7 is installed on the template lowering rack 5 and the top upper supporting plate 7 contacts the top of the template in the template outlet;

[0054] The template transverse movement assembly 8 is arranged between the top upper supporting plate 7 and the template lowering rack 5. The template transverse movement assembly 8 is installed on the second cross hanger 3 and is used to provide a force for the template lowering rack 5 to insert into the groove on the outer side of the template when the top upper supporting plate 7 is lifted by the template;

[0055] The template feeding assembly 9 is installed on the template placement rack 4 and is used to push the templates in the template placement rack 4 into the template outlet one by one and drive the bottom upper supporting plate 6 to lift the template in the template outlet.

[0056] Specifically, the templates to be laid can be pre-stacked in the template placement rack 4. When placing the templates, the templates can be put in through the template inlet on the outer side of the template placement rack 4. After the templates are placed in the template placement rack 4, they are in a vertical and closely adjacent state. When the template feeding assembly 9 operates, it first pushes the templates stacked in the template placement rack 4 inward, so that the innermost template moves into the template outlet. At this time, the template in the template outlet is supported by the bottom upper supporting plate 6. Then, the template feeding assembly 9 drives the bottom upper supporting plate 6 to move upward. The bottom upper supporting plate 6 lifts the template in the template outlet. At this time, this template lifts the top upper supporting plate 7. During the upward movement of the top upper supporting plate 7, the template transverse movement assembly 8 generates a force to move the template lowering rack 5 inward, so that the template lowering rack 5 is inserted into the groove on the outer side of the template from the outside to the inside. At this time, the template lowering rack 5 can support the template by supporting the top edge of the template. Finally, by the lowering of the second cross hanger 3, the template lowering rack 5 can lower the template to the ground, and the lowered templates are respectively beside the steel bars tied to the four side walls of the single crystal furnace.

[0057] Such as Figure 1 And Figure 2As shown in the figure, a first hoist 10 is provided on the top of the walking frame 1. Two sets of first lifting wheels 11 are connected to the power shaft of the first hoist 10. A first sling 12 is wound around the four first lifting wheels 11, and the bottom ends of the four first slings 12 are connected to the top of the first cross hanger 2. At this time, by controlling the first hoist 10, the height of the template placement rack 4 can be adjusted by using the first lifting wheels 11 and the first sling 12. When adding templates to the template placement rack 4, the template placement rack 4 can be lowered to the ground as a whole. When using the displacement device of the walking frame 1 as a whole, the template placement rack 4 can be lifted to a height greater than the height of the tied steel bars on the side wall of the single crystal furnace, so as to facilitate the device to shuttle and walk in the single crystal furnace foundation group.

[0058] A second hoist 13 is provided on the top of the first cross hanger 2. Two sets of second lifting wheels 14 are connected to the power shaft of the second hoist 13. A second sling 15 is wound around the four second lifting wheels 14, and the bottom ends of the four second slings 15 are connected to the top of the second cross hanger 3. At this time, by controlling the second hoist 13, the height of the template lowering rack 5 can be adjusted by using the second lifting wheels 14 and the second sling 15, realizing the process of lowering the template and resetting the template lowering rack 5.

[0059] As Figure 9 shown, the template placement rack 4 includes a top plate 4-1, a bottom plate 4-2, two side frames 4-3 and two pairs of connecting rods 4-4. The top plate 4-1 and the bottom plate 4-2 are arranged vertically. The two side frames 4-3 are respectively arranged on both sides of the top plate 4-1 and the bottom plate 4-2. The two pairs of connecting rods 4-4 connect the four corners of the two side frames 4-3 respectively, and the top plate 4-1 and the bottom plate 4-2 are respectively sleeved on a pair of connecting rods 4-4 located above and below.

[0060] Specifically, the area enclosed by the top plate 4-1, the floor, the side frame 4-3 and the connecting rod 4-4 is used to place templates, and the outside of this area is the template entrance, and the inside of this area is the template exit. The top plate 4-1 and the bottom plate 4-2 are located in the middle between the two side frames 4-3, and the top plate 4-1 and the floor are respectively in contact with the top and bottom of the template.

[0061] As Figure 3 、 Figures 5 to 7 and Figure 16As shown in the figure, the template feeding assembly 9 includes a feeding conveyor belt 9-1, a first feeding gear set 9-2, a second feeding gear set 9-3, a feeding ratchet gear 9-4, a locking ratchet block 9-5, a feeding ratchet rack 9-6, and an electric push rod 9-7. A feeding conveyor belt 9-1 is sleeved between the same-side ends of each pair of connecting rods 4-4. The two conveyor belts are used to support the two sides of the top and bottom of the template respectively. The top plate 4-1, the bottom plate 4-2, and the side frame 4-3 are all rotatably connected to the connecting rod 4-4. The end parts of the upper and lower two connecting rods 4-4 on the same side of the side frame 4-3 are respectively connected to the feeding ratchet gear 9-4 through the first feeding gear set 9-2 and the second feeding gear set 9-3. One feeding ratchet rack 9-6 is provided corresponding to each of the two feeding ratchet gears 9-4. The two feeding ratchet racks 9-6 are connected by a sliding rod. The sliding rod is slidably installed on the side frame 4-3 in the height direction, and the sliding rod is connected to the extending end of the electric push rod 9-7. The locking ratchet block 9-5 is rotatably installed on the side frame 4-3, and its bottom end meshes with the feeding ratchet gear 9-4 to lock the template in the template placement rack 4 from displacing towards the template outlet. The ratchet teeth of the feeding ratchet rack 9-6 are telescopic teeth. Specifically, the feeding ratchet rack 9-6 is configured to include a plate body, ratchet teeth, and a ratchet spring. The ratchet teeth are telescopically installed on the plate body, and the ratchet spring is arranged between the plate body and the ratchet teeth.

[0062] Specifically, the first feeding gear set 9-2 includes three circular gears, and the second feeding gear set includes four circular gears, so that when the two feeding ratchet racks 9-6 rise or fall simultaneously, the rotation directions of the two feeding conveyor belts 9-1 are the same.

[0063] Template feeding process: When the electric push rod 9-7 is started to cause the feeding ratchet rack 9-6 to displace downward, the two feeding ratchet racks 9-6 distributed up and down respectively drive the two feeding ratchet gears 9-4 to rotate. The two feeding ratchet gears 9-4 respectively drive the first feeding gear set 9-2 and the second feeding gear set 9-3 to act. At this time, the opposite sides of the two feeding conveyor belts 9-1 both rotate inward, and then push the template in the template placement rack 4 towards the template outlet side until the innermost template enters the template outlet, and this template lands on the bottom upper support plate 6, and the bottom of this template contacts the top upper support plate 7.

[0064] During the rotation of the feeding ratchet gear 9-4, the locking ratchet block 9-5 can lock the feeding ratchet gear 9-4 in real time to prevent the feeding ratchet gear 9-4 from rotating in the reverse direction, resulting in the template in the template placement rack 4 displacing outward. This not only prevents the template from moving out of the template outlet but also prevents the template from becoming loose and falling over.

[0065] Template feeding reset process: When the electric push rod 9-7 is started to reset the feeding ratchet rack 9-6 upward, since the feeding ratchet gear 9-4 is locked by the locking ratchet and cannot rotate in the reverse direction, furthermore, during the upward displacement of the feeding ratchet rack 9-6, its ratchet teeth compress the ratchet spring and contract into the plate body to cross over the feeding ratchet rack 9-6. During this process, the template in the template placement rack 4 remains stationary.

[0066] As Figure 3 , Figure 5 , Figure 12 and Figure 13 shown, the template feeding assembly 9 further includes a first upper top rack 9-8, a first upper top gear 9-9, an upper top screw 9-10, an upper top screw sleeve 9-11, an upper top guide sleeve 9-12, an upper top guide rod 9-13, an upper top spiral groove 9-14, an upper top guide ball 9-15, a second upper top gear 9-16, a second upper top rack 9-17, a baffle 9-18, a torsion spring, a feeding straight groove 9-19 and a feeding spiral groove 9-20. The first upper top rack 9-8 is fixedly installed on the slide rod. The first upper top gear 9-9 is fixedly installed on the outer end of the upper top screw 9-10, and the first upper top gear 9-9 meshes with the first upper top rack 9-8. The two ends of the upper top screw 9-10 are respectively rotatably installed on the side frame 4-3. The upper top screw sleeve 9-11 is threadedly sleeved on the upper top screw 9-10. The upper top guide sleeve 9-12 is fixedly installed at the bottom end of the upper top screw sleeve 9-11. The upper top guide rod 9-13 passes through the upper top guide sleeve 9-12, and both ends of the upper top guide rod 9-13 are rotatably installed on the side frame 4-3. The second upper top gear 9-16 is fixedly installed on the inner end of the upper top guide rod 9-13. The bottom end of the second upper top rack 9-17 is connected to the end of the bottom upper support plate 6. The second upper top rack 9-17 is slidably installed in the height direction on the side frame 4-3, and the second upper top gear 9-16 meshes with the second upper top rack 9-17. The baffle 9-18 is rotatably sleeved outside the inner end of the upper top guide rod 9-13, and the baffle 9-18 is located inside the template outlet in the template feeding direction. The torsion spring is arranged between the baffle 9-18 and the upper top guide rod 9-13. The upper top bolt groove, the feeding straight groove 9-19 and the feeding spiral groove 9-20 are axially opened from the inside to the outside on the outer side of the upper top guide rod 9-13. The upper top guide ball 9-15 is fixedly installed on the inner wall surface of the upper top guide sleeve 9-12. The upper top guide ball 9-15 displaces inward in the feeding spiral groove 9-20 to drive the upper top guide rod 9-13 to turn the baffle 9-18 out of the template outlet. The feeding straight groove 9-19 is used to adapt to the translation process of the template entering the template outlet. When the upper top guide ball 9-15 displaces inward in the upper top spiral groove 9-14, the bottom upper support plate 6 jacks up the template in the template outlet.

[0067] Specifically, the baffle 9-18 is located inside the template outlet in the initial state. At this time, the baffle 9-18 can prevent the template in the template placement rack 4 from tipping inward, improving the stability of the template.

[0068] During the above-mentioned template feeding process, the descending stroke of the feeding ratchet rack 9-6 is divided into a first descending stroke, a second descending stroke, and a third descending stroke, where:

[0069] In the first descending stroke, the feeding ratchet rack 9-6 switches from the separated state from the feeding ratchet gear 9-4 to the meshing state, and the first upper lifting rack 9-8 drives the first upper lifting gear 9-9 to rotate. The first upper lifting gear 9-9 drives the upper lifting screw 9-10 to rotate, and the upper lifting screw 9-10 drives the upper lifting nut 9-11 to displace inward. At this time, the upper lifting nut 9-11 drives the upper lifting guide sleeve 9-12 to displace inward outside the upper lifting guide rod 9-13, and the upper lifting guide ball 9-15 drives the upper lifting guide rod 9-13 to rotate during the inward displacement in the feeding spiral groove 9-20. At this time, the upper lifting guide rod 9-13 drives the baffle 9-18 to rotate upward, so that the baffle 9-18 rotates out of the template outlet, and the second upper lifting gear 9-16 drives the second upper lifting rack 9-17 to rise, and the second upper lifting rack 9-17 drives the bottom upper supporting plate 6 to displace upward to below the template outlet.

[0070] In the second descending stroke, the upper lifting guide ball 9-15 displaces in the feeding straight groove 9-19, and the feeding ratchet rack 9-6 drives the feeding ratchet gear 9-4 to rotate, realizing the feeding process of the template. During this process, the template in the template placement rack 4 displaces inward, so that the innermost template enters the template outlet.

[0071] In the third descending stroke, the feeding ratchet rack 9-6 is in a separated state from the feeding ratchet gear 9-4, and the upper lifting guide ball 9-15 displaces in the upper lifting spiral groove 9-14. At this time, the upper lifting guide rod 9-13 rotates, and the upper lifting guide rod 9-13 drives the second upper lifting gear 9-16 to rotate. The second upper lifting gear 9-16 drives the second upper lifting rack 9-17 to rise, and the second upper lifting rack 9-17 drives the bottom upper supporting plate 6 to displace upward. At this time, the bottom upper supporting plate 6 jacks up the template in the template outlet, and the jacked-up template jacks up the top upper supporting plate 7. During the upward displacement of the top upper supporting plate 7, the template transverse movement assembly 8 provides a force for the template lowering rack 5 to displace inward and insert into the groove on the outer side of the template. After completing the above-mentioned third descending stroke, the baffle 9-18 is in a downward state.

[0072] In the above-mentioned template feeding reset process: the baffle 9-18 rotates upward from the outside and then rotates into the template outlet. During this process, since the template inside the template outlet has not been lowered yet, after the upper guide sleeve 9-12 returns to its initial position, the top end of the baffle 9-18 abuts against the side surface of the template inside the template outlet. At this time, the torsion spring is compressed. When the template is lowered and disengages from the top end of the top plate 4-1, before the lowered template disengages from the template outlet, the lowered template has a limiting effect on the template in the template placement rack 4, so that the template in the template placement rack 4 is located outside the template outlet and will not hinder the rotational reset of the baffle 9-18. Furthermore, the baffle 9-18 will automatically rotate into the template outlet under the action of the torsion spring. While the baffle 9-18 realizes its own reset, it limits the inner side of the template on the template placement rack 4.

[0073] As Figure 4 , Figure 10 , Figure 11 and Figure 14 shown, the template lowering rack 5 includes a lowering rack connecting seat 5-1, a first lowering connecting plate 5-2, a second lowering connecting plate 5-3, a third lowering connecting plate 5-4, a fourth lowering connecting plate 5-5 and a lowering plate 5-6. The lowering rack connecting seat 5-1 is installed at the end of the second cross hanger 3. The first lowering connecting plate 5-2 is horizontally displaceably installed on the lowering rack connecting seat 5-1. The second lowering connecting plate 5-3 is vertically and fixedly installed at the bottom of the lowering rack connecting seat 5-1. The top end and the middle part of the third lowering connecting plate 5-4 are respectively rotationally connected to the first lowering connecting plate 5-2 and the second lowering connecting plate 5-3. The top of the fourth lowering connecting plate 5-5 is connected to one end of the third lowering connecting plate 5-4 away from the first lowering connecting plate 5-2. The lowering plate 5-6 is installed at the bottom end of the fourth lowering connecting plate 5-5. The lowering plate 5-6 includes a horizontally arranged first transverse plate body part 5-6a and a first longitudinal plate body part 5-6b vertically arranged at the inner bottom end of the first transverse plate body part 5-6a. The first transverse plate body part 5-6a is used to support on the inner top wall of the groove on the outer side surface of the template, and the first longitudinal plate body part 5-6b is used to contact the inner side wall of the groove on the outer side surface of the template.

[0074] As Figure 10 and Figure 14 shown, the top upper support plate 7 includes a horizontally arranged second transverse plate body part 7-1 and a second longitudinal plate body part 7-2 vertically arranged at the inner bottom end of the second transverse plate body part 7-1. The initial height of the second transverse plate body part 7-1 is less than that of the first longitudinal plate body part 5-6b, and when the second transverse plate body part 7-1 moves upward, its outer end contacts the first longitudinal plate body part 5-6b. The outer side surface of the second longitudinal plate body part 7-2 contacts the inner side surface of the template inside the template outlet, and the bottom of the second transverse plate body part 7-1 contacts the top of the template inside the template outlet.

[0075] Specifically, when the template is located inside the template outlet, the top of the template contacts the bottom of the second horizontal plate body part 7-1, and the inner side surface of the template contacts the second vertical plate body part 7-2. At this time, the top of the template is effectively limited, and the template can be kept in an upright state.

[0076] As Figure 8 and Figure 9 shown, the bottom upper supporting plate 6 includes a third horizontal plate body part 6-1 supported on the bottom of the template, a third vertical plate body part 6-2 vertically arranged on the top of the third horizontal plate body part 6-1, and an end plate 6-3 connected between the ends of the third horizontal plate body part 6-1 and the third vertical plate body part 6-2. A guide rail 22 is fixedly arranged on the side frame 4-3. A pair of guide wheels 23 that clamp the guide rail 22 from both sides are arranged on the guide rail 22, and the two guide wheels 23 are connected by a wheel frame. A support plate 24 is rotatably connected to the surface of the wheel frame. One end of the support plate 24 away from the wheel frame is rotatably connected to the end plate 6-3. A transmission plate 25 is rotatably connected to the end plate 6-3. One end of the transmission plate 25 away from the end plate 6-3 is rotatably connected to the bottom end of the second upper top rack 9-17.

[0077] Specifically, in the initial state, the bottom upper supporting plate 6 is located below the template placement rack 4 and is located outside the template outlet in the inner and outer directions. When the feeding ratchet rack 9-6 performs the above-mentioned first descending stroke and the second upper top rack 9-17 rises upward, through the cooperation of the transmission plate 25, the support plate 24, the wheel frame, the guide wheels 23 and the guide rail 22, the bottom upper supporting plate 6 swings to a horizontal state. At this time, the top upper supporting plate 7 is exactly located directly below the template outlet, so that when the innermost template enters the template outlet, it can directly fall on the top of the bottom upper supporting plate 6.

[0078] The guide rail 22 includes a vertical section for guiding the bottom upper supporting plate 6 to rise vertically to lift the template, and an arc section with a central angle of 90° connected to the bottom end of the vertical section. The arc section is used for the bottom upper supporting plate 6 to enter directly below the template outlet from bottom to top or leave the template outlet from top to bottom. Furthermore, when the feeding ratchet rack 9-6 performs the above-mentioned template feeding reset process, the bottom upper supporting plate 6 will return to its initial position again. At this time, a passage is provided for the template lowering frame 5 to lower the template, preventing the bottom upper supporting plate 6 from obstructing the lowering of the template.

[0079] As Figure 4 、 Figure 11 、 Figure 14 and Figure 15As shown, the template transverse movement assembly 8 includes a lifting ratchet rack 8-1, a template transverse movement ratchet gear 8-2, a template transverse movement circular gear 8-3, a translation rack 8-4, an elastic telescopic rod 8-5 and a transverse pushing spring 8-6. The fixed end of the elastic telescopic rod 8-5 is slidably installed on the lower support connection base 5-1, and the top end of the first lower connecting plate 5-2 is connected to the movable end of the elastic telescopic rod 8-5. The translation rack 8-4 is fixedly installed on the side surface of the fixed end of the elastic telescopic rod 8-5. The template transverse movement ratchet gear 8-2 is rotatably installed on the lower support connection base 5-1. The template transverse movement circular gear 8-3 is coaxially installed on one side of the template transverse movement ratchet gear 8-2, and the bottom of the template transverse movement circular gear 8-3 meshes with the translation rack 8-4. The bottom end of the lifting ratchet rack 8-1 is fixedly connected to the top upper support plate 7. The lifting ratchet rack 8-1 vertically penetrates through the lower support connection base 5-1, and the lifting ratchet rack 8-1 meshes with the teeth on the inner side direction of the template transverse movement ratchet gear 8-2. The ratchet teeth of the lifting ratchet rack 8-1 can stretch and contract. The structure of the lifting ratchet rack 8-1 is set to be similar to that of the feeding ratchet rack 9-6.

[0080] Specifically, when the top upper support plate 7 rises, it pushes the lifting ratchet rack 8-1 to rise. The lifting ratchet rack 8-1 drives the template transverse movement ratchet gear 8-2 to rotate. The template transverse movement ratchet gear 8-2 then drives the translation rack 8-4 to displace inwards through the template transverse movement circular gear 8-3. The translation rack 8-4 drives the fixed end of the elastic telescopic rod 8-5 to displace inwards and compress the transverse pushing spring 8-6. At this time, since the outer end of the second transverse plate portion 7-1 contacts the first longitudinal plate portion 5-6b, the second transverse plate portion 7-1 has a limiting effect on the first longitudinal plate portion 5-6b, which can prevent the template lower support 5 from displacing inwards. Furthermore, the extending end of the elastic telescopic rod 8-5 is fixed, and thus, the spring of the elastic telescopic rod 8-5 is stretched.

[0081] As the top upper support plate 7 and the template in the template outlet are lifted to a height where the bottom of the template top edge is greater than the height of the first transverse plate portion 5-6a, the first lower connecting plate 5-2 quickly displaces inwards under the action of the elastic telescopic rod 8-5, causing the top end of the third lower connecting plate 5-4 to rotate inwards and the bottom end to rotate outwards. At this time, the third lower connecting plate 5-4 causes the top end of the fourth lower connecting plate 5-5 to rotate outwards and the bottom end to rotate inwards. Furthermore, the fourth lower connecting plate 5-5 drives the lower plate 5-6 to displace inwards and insert into the groove on the outer side of the template.

[0082] After the lowering plate 5-6 is inserted into the groove on the outer side of the template, the outer side of the entire template lowering frame 5 is located inside the template outlet in the inner and outer directions, facilitating the smooth lowering of the template. At the same time, since the lifting ratchet rack 8-1 meshes with the template transverse movement ratchet gear 8-2, and the template is supported by the first transverse plate portion 5-6a, which has the function of preventing the lifting rack from descending. As a result, the transverse push spring 8-6 and the elastic telescopic rod 8-5 are locked in the inner and outer directions, achieving the positioning of the template. After that, the second hoist 13 can be started to lower the template lowering frame 5 to achieve the effect of lowering the template.

[0083] A pressing spring 16 is provided between the bottom of the top supporting plate 7 and the bottom of the lowering frame connecting seat 5-1. The pressing spring 16 is compressed during the upward movement of the lifting ratchet rack 8-1. After the template is placed on the ground, the template lowering frame 5 is continuously lowered. The lifting ratchet rack 8-1 continues to move upward and disengages from the template transverse movement ratchet gear 8-2. At this time, the elastic telescopic rod 8-5 quickly moves outward under the action of the transverse push spring 8-6 and drives the first lowering connecting plate 5-2 and the lowering plate 5-6 to move outward and reset horizontally, so that the lowering plate 5-6 is withdrawn from the groove on the outer side of the template to disengage from the template.

[0084] After that, the second hoist 13 is started to raise the template lowering frame 5. The lifting ratchet rack 8-1 will move downward under the action of gravity and the pressing spring 16. During the process that the ratchet teeth of the lifting ratchet rack 8-1 pass through the template transverse movement ratchet gear 8-2, the ratchet teeth of the lifting ratchet rack 8-1 contract to cross over the transverse movement ratchet gear. And during this process, the elastic telescopic rod 8-5 remains in place under the action of the transverse push spring 8-6. When the lifting ratchet rack 8-1 descends to the initial height, it remains in the meshing state with the template transverse movement ratchet gear 8-2.

[0085] During the process of the overall upward reset of the template lowering frame 5, since the fourth lowering connecting plate 5-5 is in a state where the top end inclines inward, therefore, during the upward movement of the fourth lowering connecting plate 5-5 past the template placing frame 4, the fourth lowering connecting plate 5-5 will contact the template placing frame 4 and then perform a movement of rotating the top end outward and the bottom end inward to cross over the template placing frame 4. And during the process that the fourth lowering connecting plate 5-5 performs this movement, the extending end of the elastic telescopic rod 8-5 is pulled outward, stretching the spring of the elastic telescopic rod 8-5. When the fourth lowering connecting plate 5-5 together with the lowering plate 5-6 is completely out of the blockage of the template placing frame 4, under the action of the elastic telescopic rod 8-5, the fourth lowering connecting plate 5-5 together with the lowering plate 5-6 automatically resets.

[0086] It should be noted that, in the initial state, the initial height of the second horizontal plate body part 7-1 is less than that of the first vertical plate body part 5-6b. Therefore, when the template lowering frame 5 rises integrally past the template placing frame 4, the height of the second horizontal plate body part 7-1 is less than that of the first vertical plate body part 5-6b. As a result, when the fourth lowering plate 5-6 body part rotates inward through the bottom end past the template placing frame 4, the fourth lowering connecting plate 5-5 can swing the lower plate above the top upper support plate 7.

[0087] As Figure 1 , Figure 2 and Figure 14 shown, a support plate 17 is fixedly arranged on the top of the top plate 4-1. The top end of the support plate 17 is fixedly connected with a placing frame connecting seat 18. The first cross hanger 2 includes four first cross beams 2-1 distributed symmetrically about the center. The second cross hanger 3 includes four second cross beams 3-1 distributed symmetrically about the center. The inner end of the placing frame connecting seat 18 is rotatably installed at the end of the first cross beam 2-1 through a first mounting shaft. The inner end of the lowering frame connecting seat 5-1 is rotatably installed at the end of the second cross beam 3-1 through a second mounting shaft. The first mounting shaft is located directly above the second mounting shaft, and the first mounting shaft and the second mounting shaft are coaxially arranged. Two bolt holes 18 are provided on both the first cross beam 2-1 and the second cross beam 3-1. The two bolt holes 18 are symmetrically distributed in the inner and outer directions on both sides of the first mounting shaft. And positioning bolts 19 for inserting into the bolt holes 18 are provided at the inner ends of both the placing frame connecting seat 18 and the lowering frame connecting seat 5-1. And both the first cross beam 2-1 and the second cross beam 3-1 are arranged to be adjustable in length.

[0088] Specifically, through the lowering frame connecting seat 5-1 and the placing frame connecting seat 18, they can be rotated to the outward or inward state on the first cross beam 2-1 and the second cross beam 3-1 respectively, and are positioned through the cooperation of the bolt holes 18 and the positioning bolts 19, which can be respectively used for laying the inner template and the outer template on the side wall of the single crystal furnace foundation, further improving the efficiency of the construction operation. Specifically, when laying the inner template on the side wall of the single crystal furnace foundation, the template placing frame 4 can be made to be located in the inner direction of the template lowering frame 5 by rotating the lowering frame connecting seat 5-1 and the placing frame connecting seat 18.

[0089] The first cross beam 2-1 and the second cross beam 3-1 are both arranged as telescopic two-beam structures, and the two-beam structures are connected by an adjusting long bolt 20 and an adjusting sleeve 21. Specifically, one end of the adjusting long bolt 20 is rotatably installed on one of the beam structures, the adjusting sleeve 21 is installed on the other beam structure, and the adjusting long bolt 20 is threadedly connected to the adjusting sleeve 21. Therefore, by rotating the adjusting long bolt 20, the function of adjusting the lengths of the first cross beam 2-1 and the second cross beam 3-1 can be achieved. At this time, the distance between the formwork lowering frame 5 and the steel bars tied to the side wall part of the single crystal furnace can be adjusted to ensure the smooth lowering of the formwork of the formwork lowering frame 5. Then, the position of the formwork placing frame 4 is adjusted with reference to the inner and outer positions of the formwork lowering frame 5 to make the positions between the formwork lowering frame 5 and the formwork placing frame 4 correct, so as to fully ensure the implementation of the formwork lowering.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
