Description

Technical Field

[0001] The invention belongs to the field of slope support, and in particular relates to a steel bar inserting device for slope support. Background Art

[0002] As people's lives develop faster and faster, there are more and more construction projects, more and more types of construction projects, and more and more foundation pit construction projects. Slope support is a very important step in foundation pit construction. Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its environment.

[0003] The usual way of slope support is to first evenly lay steel bars on the slope, hang mesh on the steel bars, and then pour concrete to complete the slope support.

[0004] Since the mesh needs to be laid well on the slope, during the process of inserting the steel bars, it is necessary to use measuring tools such as tape measures to position the steel bars, and then insert the steel bars into the slope. However, some slopes are relatively soft, and after one end of the steel bar is inserted into the slope, the other end of the steel bar exposed outside the slope is easy to loosen. Under the action of external force or in the process of hanging the mesh, the construction workers' misoperation will cause the steel bars to be inaccurately positioned. If the soft slope is compacted every time, the cost will be too high. Summary of the invention

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 to Figure 5 A steel bar insertion device for slope support includes an equipment platform 1, four self-locking universal wheels 11 are arranged at the bottom of the equipment platform 1, a driving cylinder 2, a feeding platform 5 corresponding to the number of the driving cylinders 2, and a storage bin 4 for storing steel bars 8 are arranged on the upper part of the equipment platform 1.

[0026] Reference Figure 1 The steel bars 8 come out of the stock bin 4 and are fed into the driving cylinder 2 through the feeding table 5. The equipment table 1 moves to the position where the steel bars 8 need to be inserted into the slope, and then the position of the driving cylinder 2 is adjusted to allow the feeding table 5 to feed the steel bars 8 in the stock bin 4 into the driving cylinder 2. The steel bars 8 are inserted into the slope through the driving cylinder 2.

[0027] In the present application, there are two feeding platforms 5 and two driving cylinders 2 , and the stock warehouse 4 feeds materials to the two feeding platforms 5 .

[0028] Reference Figure 2 and Figure 3 A cavity 43 is provided inside the stocking bin 4, and the stocking bin 4 is provided with a feed port 431 and a discharge port 432 which are connected with the cavity 43. The feed port 431 is provided above the stocking bin 4, so that the staff can put the steel bars 8 into the stocking bin 4 conveniently. There are two discharge ports 432, which correspond to two feeding platforms 5 respectively. The discharge ports 432 are opened downward, and each discharge port 432 is provided with a limiting component 6, which is used to limit the steel bars 8 in the cavity 43 from coming out of the discharge port 432.

[0029] Reference Figure 2 and Figure 3Each feeding platform 5 has a pushing end 52 , and the feeding platform 5 can push the limiting component 6 when moving, so that the limiting component 6 opens the discharge port 432 , thereby allowing the steel bar 8 to fall into the feeding platform 5 .

[0030] Reference Figure 2 and Figure 3 The limiting assembly 6 includes a limiting plate 62, a limiting elastic member 63, a one-way rotating plate 64 and a limiting groove 61. The limiting groove 61 is opened in the stocking bin 4, and one end of the limiting groove 61 is connected to the discharge port 432; the lower end of the limiting groove 61 is connected to the outside, the limiting plate 62 is slidably arranged in the limiting groove 61, the limiting plate 62 is L-shaped, one end of the limiting plate 62 comes out of the limiting groove 61 and is located in the discharge port 432, the limiting elastic member 63 is a spring, and one end of the limiting elastic member 63 is connected to the limiting plate 6 2, and the other end is connected to the groove wall of the limiting groove 61. The limiting elastic member 63 can push the limiting plate 62, forcing one end of the limiting plate 62 at the discharge port 432 to abut against the side wall of the discharge port 432, thereby blocking the side wall. The other end of the limiting plate 62 extends downward from the limiting groove 61 and is located below the stocking bin 4. This position is the bottom end of the limiting plate 62. The one-way rotating plate 64 is rotatably arranged on this side of the limiting plate 62, and the one-way rotating plate 64 is located in the moving path of the pushing end 52.

[0031] Reference Figure 2 and Figure 3 The feeding platform 5 also has a receiving arc groove 51. The equipment platform 1 is provided with a cylinder for driving the feeding platform 5 to move, so that the feeding platform 5 can move relative to the stocking bin 4. When the feeding platform 5 moves toward the stocking bin 4, the pushing end 52 of the feeding platform 5 will push the one-way rotating plate 64. At this time, the one-way rotating plate 64 will not rotate, but drive the limit plate 62 to move, so that one end of the limit plate 62 at the discharge port 432 moves, so that the discharge port 432 is opened, and the steel bars 8 in the stocking bin 4 come out of the discharge port 432 and enter the receiving arc groove 51 of the feeding platform 5. Then the feeding platform 5 is reset again. At this time, if the movement of the feeding platform 5 touches the one-way rotating plate 64, the one-way rotating plate 64 will rotate, so that the movement of the feeding platform 5 will not affect the limit plate 62, and the limit elastic member 63 will push the limit plate 62, so that one end of the limit plate 62 continues to block the discharge port 432.

[0032] Reference Figure 2 and Figure 3The cam 73 is provided with a plurality of anti-roll convex strips 73 at the top of the anti-roll plate 72, and the anti-roll convex strips 73 are provided with a plurality of anti-roll convex strips 73 at the bottom of the anti-roll plate 72. As the anti-roll plate 72 moves up and down, the anti-roll convex strips 73 can enter the cavity 43 from the anti-roll groove 71 or enter the anti-roll groove 71 from the cavity 43. Two adjacent anti-roll convex strips 73 can limit the steel bar 8 in the cavity 43 to prevent the steel bar 8 from rolling and overlapping. The anti-roll elastic member 74 is a spring, which can When the locking cam 75 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is locked in the unlocked position.

[0033] Reference Figure 2 and Figure 3 The steel bars 8 in the stock bin 4 are blocked by the anti-rolling ridges 73. When the limiting plate 62 moves to open the discharge port 432, the limiting plate 62 will simultaneously pull the pull rope 75, allowing the pull rope 75 to pull the anti-rolling ridges 73 out of the cavity 43 and into the anti-rolling groove 71. At this time, the anti-rolling ridges 73 no longer limit the steel bars 8, and the steel bars 8 can roll in the cavity 43, so that one of the steel bars 8 rolls out of the discharge port 432 and enters the receiving arc groove 51 of the feeding table 5.

[0034] Reference Figure 1The stocking bin 4 is also provided with a push driving rod 41, which is the driving end of the cylinder, and a push plate 42 is connected to the push driving rod 41, and the push plate 42 is V-shaped. The side wall of the stocking bin 4 is provided with a push groove 44 connected to the cavity 43. The arrangement of the steel bars 8 in the cavity 43 can be seen from the outside of the push groove 44. When the push plate 42 is V-shaped, the push plate 42 can push the steel bars 8 on the arc groove 51, so that the steel bars 8 on the feeding platform 5 can enter the driving cylinder 2. When it is necessary to sort the steel bars 8 in the stocking bin 4, the push plate 42 is rotated to make the push plate 42 in an inverted V shape. At this time, the push plate 42 is driven, and the push plate 42 can enter the push groove 44, so that the steel bars 8 can be pushed more neatly.

[0035] Reference Figure 1 The equipment platform 1 is provided with a transverse moving platform 12, and the equipment platform 1 is equipped with a lead screw. The transverse moving platform 12 is driven by the lead screw to move along the transverse direction of the equipment platform 1, so as to control the distance between two adjacent driving cylinders 2. The driving cylinder 2 is slidably arranged on the transverse moving platform 12. The equipment platform 1 is also provided with a longitudinal driving member 13 for longitudinally moving the driving cylinder 2 relative to the transverse moving platform 12. The longitudinal driving member 13 is a cylinder, and a telescopic plate is arranged at the output end of the longitudinal driving member 13. The telescopic plate is connected to the driving cylinder 2. The telescopic plate can prevent the transverse movement of the driving cylinder 2 from interfering with the longitudinal driving member 13, and can realize that the longitudinal driving member 13 can push the two driving cylinders 2 to move longitudinally at any position of the two driving cylinders 2. The longitudinal movement is mainly used to move the driving cylinder 2 toward the slope direction, so that the working end of the driving cylinder 2 is inserted into the slope.

[0036] Reference Figure 1 The working end of the driving cylinder 2 is detachably provided with an embedded cylinder 3, and the embedded cylinder 3 is hollow inside to allow the steel bar 8 to pass through. When the feeding platform 5 moves, the axis of the arc groove 51 can be aligned with the axis of the embedded cylinder 3. When the arc groove 51 is aligned with the embedded cylinder 3, the steel bar 8 passes through the driving cylinder 2 and enters the embedded cylinder 3 under the push of the flat push plate 42.

[0037] Reference Figure 1 The driving cylinder 2 is equipped with an active transmission roller 21 and a driven transmission roller 22 for driving the steel bars 8. When the steel bars 8 enter the driving cylinder 2, the active transmission roller 21 and the driven transmission roller 22 drive the steel bars 8 in the driving cylinder 2 to come out from one end of the embedded cylinder 3 and be inserted into the slope.

[0038] Reference Figure 1 and Figure 4The embedded tube 3 has an insertion end 31 and a compacting end 32. The insertion end 31 is a slender round rod with a thinner end, so that when the longitudinal driving member 13 pushes the driving tube 2, the insertion end 31 of the embedded tube 3 is inserted into the slope. The compacting end 32 is conical. After the insertion end 31 is inserted into the slope, the compacting end 32 continues to be inserted into the slope. The compacting end 32 can squeeze and compact the soil on the surface of the slope, thereby improving the density of the slope soil at this position and achieving a compaction effect.

[0039] Reference Figure 4 and Figure 5 The compacting end 32 is provided with an annular groove 33, the driving cylinder 2 is provided with a groove 23, and a clamping member 24 is arranged in the groove 23. Under the action of the clamping member 24, the embedded cylinder 3 and the driving cylinder 2 are disassembled and connected in a clamping manner. After the embedded cylinder 3 is installed on the working end of the driving cylinder 2, the annular groove 33 can be connected with the groove 23. At this time, the output end of the clamping member 24 is located in the annular groove 33.

[0040] Reference Figure 4 and Figure 5 The clamping member 24 includes a clamping spring 241 and a clamping ball 242 . The clamping ball 242 is the output end of the clamping member 24 . One end of the clamping spring 241 is connected to the clamping ball 242 and has a tendency to push the clamping ball 242 to move toward the annular groove 33 .

[0041] Reference Figure 4 and Figure 5 The compacting end 32 is provided with a through groove 34 connected to the annular groove 33, and an unlocking block 35 is slidably arranged in the through groove 34. There are multiple through grooves 34, and there are also multiple unlocking blocks 35. One of the unlocking blocks 35 is hidden in the figure. The unlocking block 35 has a contact surface 351 and an unlocking portion 352. The contact surface 351 is an end surface of the unlocking block 35 extending out of one end of the through groove 34, and the end surface faces the insertion end 31 of the embedded cylinder 3. The unlocking portion 352 of the unlocking block 35 is located inside the through groove 34, and the unlocking portion 352 can push the locking ball 242 into the groove 23.

[0042] Reference Figure 4 and Figure 5 The embedded tube 3 is internally connected with a barb 36 , and the end of the barb 36 faces the outlet side of the embedded tube 3 . After the steel bar 8 enters the embedded tube 3 from the driving tube 2 , the barb 36 can restrict the steel bar 8 from coming out of the driving tube 2 .

[0043] The implementation principle of the embodiment is as follows: the construction personnel first load the steel bars 8 into the stocking bin 4, then move the equipment platform 1 to the designated position, adjust the transverse moving platform 12, move the transverse moving platform 12, thereby adjusting the relative position of the driving cylinder 2, and then the feeding platform 5 takes the steel bars 8 from the stocking bin 4, and then enters the driving cylinder 2 under the push of the push plate 42.

[0044] After the embedded cylinder 3 is aligned with the position where the steel bar 8 needs to be inserted, the longitudinal driving member 13 is started to insert the embedded cylinder 3 into the surface layer of the slope. The embedded cylinder 3 can compact the slope, and then the driving cylinder 2 is started to allow the steel bar 8 to pass through the embedded cylinder 3 and be inserted into the slope. After the steel bar 8 enters the slope. The longitudinal driving member 13 is started again to allow the embedded cylinder 3 to be further inserted into the slope. At this time, during the insertion process, the slope will press against the unlocking surface on the unlocking block 35, allowing the embedded cylinder 3 to separate from the driving cylinder 2. In this way, the steel bar 8 and the embedded cylinder 3 are inserted into the slope, and the embedded cylinder 3 keeps compacting the surface of the slope.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the above specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.
