Technical Field

[0001] The utility model relates to the technical field of building construction aids, and particularly relates to a marble transfer device. Background Art

[0002] Marble, as a natural stone, is highly regarded for its excellent compressive strength and good physical and chemical properties. Its unique cross-section presents patterns like Chinese ink landscape paintings, making it widely used in the fields of architectural decoration and handicraft production. However, there are some problems in the process of marble transfer.

[0003] Since marble materials are usually large in size and high in weight, for a 1.8 cm thick large slab, the volume of marble per square meter is about 0.018 cubic meters, and its weight per square meter is between 47 and 52 kilograms. Using pure manual handling is not only inefficient but also requires high labor costs. Therefore, it is usually necessary to use a transfer vehicle. The existing transfer vehicles mainly have a structure composed of a vertical plate and a bottom plate, with rollers installed under the bottom plate. Although it can achieve batch and rapid handling of marble, it lacks a buffer structure and cannot achieve the effect of buffer protection. Since the construction site is usually uneven, the transfer vehicle is prone to vibration during transportation, and the marble on the transfer vehicle is easily broken due to vibration. Secondly, the stone materials required for interior decoration of large buildings are usually large in size and have many special-shaped specifications, and the existing transfer vehicles cannot meet the transportation of marble materials with multiple specifications. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the technical problem solved by the utility model is to provide a marble transfer device, which solves the problem that the existing marble transfer device lacks a buffer function, resulting in the vibration generated when the transfer vehicle moves may cause the marble to break.

[0005] To solve the above problems, the technical solution adopted by the utility model is: a marble transfer device, including a seat; universal wheels are installed at the bottom of the seat, a limiting strip is fixed vertically at the top of the seat, a U-shaped frame is fixed on the outer side wall of the limiting strip, and a U-shaped handrail is movably connected to the U-shaped frame through a movable pin; a reinforcing strip can be fixedly connected to the side wall of the limiting strip, and the bottom of the reinforcing strip is fixed to the top of the seat; soft cushion strips are arranged on the outer wall of the reinforcing strip and the top of the seat.

The fixing pin is used for limiting and cooperating with the first clamping hole, the second clamping hole and the third clamping hole for limiting. By inserting the fixing pin into the first clamping hole and the second clamping hole, the U-shaped armrest can be adjusted to the storage state or the use state.

[0009] Furthermore, the reinforcement strip is inclined, the soft cushion strip includes a horizontal cushion strip and an inclined cushion strip, the horizontal cushion strip is detachably fixed to the seat, and the inclined cushion strip is detachably fixed to the reinforcement strip.

[0010] Furthermore, a first connection groove is opened on the top of the seat, a first connection block is arranged in the first connection groove, and the first connection block is fixed to the bottom of the horizontal cushion strip; a second connection groove is opened at one end of the reinforcement strip, a second connection block is arranged in the second connection groove, and the second connection block is fixed to one end of the inclined cushion strip.

Due to the inclined reinforcing bar, the marble leans against the reinforcing bar on one side during transportation, so it is not easy to tip over to the other side. By setting different inclination angles, it can adapt to the transportation of marble stones of different sizes. Preferably, it is 30°, which can be applicable to the transportation of most stone materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The length of the reinforcing strip 4 is greater than that of the limiting strip 3, and the reinforcing strip 4 is bolted or welded to the top of the limiting strip 3. The included angle between the reinforcing strip 4 and the limiting strip 3 is 10°-60°, and in this embodiment, it is 30°.

[0030] Specifically, in the present utility model, the first connection block 7 and the second connection block 13 are respectively placed into the first connection groove 6 and the second connection groove 12, so that the first connection block 7 and the second connection block 13 are respectively clamped with the first connection groove 6 and the second connection groove 12; then the first threaded rod 10 is rotated by the first turning bar 11.

[0031] Example 2: Please refer to Figure 1 and 4 , the same parts as those in Example 1 will not be described in detail. The differences are as follows: A transporter for marble, the U-shaped armrest 20 is welded to the movable pin, the movable pin 19 is rotatably connected to the U-shaped frame 18, one end of the movable pin 19 close to the end of the U-shaped frame is fixed with an auxiliary plate 21, the outer wall of the auxiliary plate 21 is provided with a first clamping hole 23 and a second clamping hole 22, and one end of the U-shaped frame 18 is provided with a third clamping hole 24. A fixing pin 25 is clamped in the third clamping hole 24 and the first clamping hole 23. The auxiliary plate 21 is disc-shaped, and a plurality of second clamping holes 22 are arranged along the circumferential direction of the auxiliary plate. The U-shaped armrest 20 can be rotated to different angles through the plurality of second clamping holes 22 to adapt to the use of people with different heights.

[0032] Specifically, when it is necessary to use the U-shaped armrest 20 to push the transporter, first take out the fixing pin 25 from the third clamping hole 24 and the first clamping hole 23, then move the angle of the U-shaped armrest 20, and then clamp the fixing pin 25 into the third clamping hole 24 and the second clamping hole 22, and the U-shaped armrest 20 can be fixed. At this time, the transporter can be pushed by using the U-shaped armrest 20;

[0033] Similarly, when the transporter is not in use, take out the fixing pin 25 from the third clamping hole 24 and the second clamping hole 22 to release the fixation of the U-shaped armrest 20. Then move the angle of the U-shaped armrest 20, and then clamp the fixing pin 25 into the third clamping hole 24 and the first clamping hole 23 to fix the U-shaped armrest 20 and store the U-shaped armrest 20, reducing the overall occupied space and improving the space utilization rate.

[0034] Example 3: Please refer to Figure 1 and 5 , 6. The same parts as those in Example 1 and Example 2 will not be described in detail. The differences are as follows: A transporter for marble, two movable grooves 26 are symmetrically arranged on the left and right side walls of the seat 1, two receiving bars 27 are movably arranged in the two movable grooves 26, and a supporting bar 28 is fixed at one end of the two receiving bars 27; a plurality of first clamping round holes 30 are arranged on the outer wall of the receiving bar 27, and second clamping round holes 29 are arranged at the front and rear ends of the seat 1; a fixing rod 31 is clamped in the second clamping round hole 29 and one of the first clamping round holes 30.

[0035] Specifically, since the receiving bar 27 is movably arranged in the movable groove 26, and a supporting bar 28 is fixed at one end of the receiving bar 27, with the cooperation of the receiving bar 27 and the supporting bar 28, the capacity of the seat 1 can be expanded, the load-bearing capacity of the seat 1 for marble is improved, and the contact area between the marble and the seat 1 is also increased, improving the stability of the marble during transportation;

[0036] And since a plurality of first clamping round holes 30 are formed in the outer wall of the receiving strip 27, by clamping the fixing rod 31 into different first clamping round holes 30 and second clamping round holes 29, the length of the receiving strip 27 can be adjusted and the receiving strip 27 can be fixed, so that the receiving strip 27 and the supporting strip 28 can be adjusted according to different marbles, expanding the overall scope of application.

[0037] Working principle:

[0038] First, by respectively placing the first connecting block 7 and the second connecting block 13 into the first connecting groove 6 and the second connecting groove 12, and then rotating the first threaded rod 10 by the first rotating bar 11. At this time, the first threaded rod 10 moves in the first threaded hole 8. After one end of the first threaded rod 10 is clamped into the first clamping hole 9, the first connecting block 7 can be fixed. Similarly, by rotating the second threaded rod 16 by the second rotating bar 17, at this time, the second threaded rod 16 moves in the second threaded hole 14. After one end of the second threaded rod 16 is clamped into the second clamping hole 15, the second connecting block 13 can be fixed. Thus, the soft cushion strip 5 can be fixed to the outer wall of the reinforcing strip 4 and the top of the seat 1. Compared with the existing ones, in the present utility model, a soft cushion strip 5 is provided on the outer wall of the reinforcing strip 4 and the top of the seat 1. Under the action of the soft cushion strip 5, it can be avoided that the marble is broken and damaged due to vibration during movement, improving the safety during marble transportation.

[0039] Secondly, when the U-shaped armrest 20 needs to be used to push the transport cart, first take out the fixing pin 25 from the third clamping hole 24 and the first clamping hole 23, then move the angle of the U-shaped armrest 20, and then clamp the fixing pin 25 into the third clamping hole 24 and the second clamping hole 22, and the U-shaped armrest 20 can be fixed. At this time, the transport cart can be pushed by using the U-shaped armrest 20.

[0040] Similarly, when the transport cart is not in use, take out the fixing pin 25 from the third clamping hole 24 and the second clamping hole 22 to release the fixation of the U-shaped armrest 20. Then move the angle of the U-shaped armrest 20, and then clamp the fixing pin 25 into the third clamping hole 24 and the first clamping hole 23 to fix the U-shaped armrest 20 and store the U-shaped armrest 20, reducing the overall occupied space and improving the space utilization rate.

[0041] Finally, since a receiving strip 27 is movably arranged in the movable groove 26, and a supporting strip 28 is fixed at one end of the receiving strip 27. With the cooperation of the receiving strip 27 and the supporting strip 28, the seat 1 can be expanded, improving the load-bearing capacity of the seat 1 for the marble and also increasing the contact area between the marble and the seat 1, improving the stability of the marble during transportation.

[0042] And since a plurality of first clamping round holes 30 are formed in the outer wall of the receiving strip 27, by clamping the fixing rod 31 into different first clamping round holes 30 and second clamping round holes 29, the length of the receiving strip 27 can be adjusted and the receiving strip 27 can be fixed, so that the receiving strip 27 and the supporting strip 28 can be adjusted according to different marbles, expanding the overall scope of application.

[0043] Embodiment 4: The same parts as those in Embodiments 1-3 will not be described in detail. The differences are as follows. As Figure 7 shown, the horizontal cushion strip includes a flexible layer 40, and an air duct 41 is provided in the flexible layer 40. The flexible layer 40 includes a support layer 42 in a concave structure, and a deformation layer 43 connecting the two ends of the concave shape. The thickness of the support layer 42 is greater than that of the deformation layer 43. The support layer 42 can be made of rubber or memory foam; as Figure 9 shown, the deformation layer 43 includes a connecting section 44 and a deformation section 45. The connecting section 44 is made of rubber with a low deformation amount, and the deformation section 45 can be made of high-deformation materials such as TPE and TPU; as Figure 8 shown, an air extraction structure is provided at the left end of the horizontal cushion strip. The air extraction structure includes an air extraction pipe 46. The lower end of the air extraction pipe 46 is communicated with the air duct 41. A first piston is slidably connected in the air extraction pipe 46. An exhaust electric one-way valve for only allowing gas to flow from the inside of the air duct 41 to the outside is provided in the first piston. A first spring 49 is provided between the lower end of the first piston and the bottom of the air extraction pipe 46. A switch 48 is provided under the exhaust electric one-way valve. The switch 48 is electrically connected to the exhaust electric one-way valve and is used to control the opening and closing of the exhaust electric one-way valve. A pressure stabilizing valve 50 is provided on the side wall of the air extraction pipe 46. When the marble slab is placed on the horizontal cushion strip

[0044] An air charging pipe 51 is further provided on the cross bar of the seat. The left end of the air charging pipe 51 passes through the fixing strip and contacts the horizontal cushion strip, and the air duct 41 is communicated with the inside of the air charging pipe 51. A second piston 52 and a limiting ring 53 are sequentially arranged in the air charging pipe 51 from left to right. The second piston 52 is slidably connected to the air charging pipe 51. The limiting ring 53 is welded to the air charging pipe 51. A second spring 54 is connected between the second piston 52 and the limiting ring 53. An intake one-way valve for only allowing gas to enter the air duct 41 from the outside is provided in the second piston 52. A push rod 55 is connected to the right side of the second piston 52. One end of the push rod 55 is rotatably connected to the second piston 52, and the other end of the push rod 55 extends out of the air duct 41 and is provided with a rotating handle 56; as Figure 10 shown, a cover plate 57 and a fixing plate 58 are provided at the end of the air charging pipe 51. A first air hole is formed in the fixing plate 58. The fixing plate 58 is rotatably connected to the push rod 55 and welded to the air charging pipe 51. The cover plate 57 is provided with a second air hole matching the first air hole. The cover plate 57 is spline-connected to the push rod 55 and rotatably connected to the air charging pipe 51. By rotating the rotating handle 56, the cover plate 57 is rotated, and then the second air hole of the cover plate 57 is overlapped or misaligned with the first air hole, so as to realize the sealing or conduction of the air charging pipe 51.

[0045] When the marble slab is placed on the horizontal pad, the horizontal pad is deformed under pressure, so that the gaps between the bottoms of the multiple marble slabs are filled with the support layer 42 and the deformation layer 43 of the horizontal pad, thereby discharging the air in the gaps between the bottoms of the multiple marble slabs and the horizontal pad; when the horizontal pad is squeezed, the excess air flows to the left end of the horizontal pad, causing the air pressure on the left to increase, and is discharged to the outside through the pressure-stabilizing valve 50, thereby discharging the squeezed excess gas and maintaining the internal air pressure of the airway 41 stable; when the transfer vehicle moves, the exhaust electric one-way valve vibrates with the vibration of the transfer vehicle, and the switch 48 is pressed when the exhaust electric one-way valve moves downward. After the switch 48 is pressed, the electric valve is opened for 0.1-0.5S and then closed, thereby making the air inside the airway 41 A part of the body is drawn out, and the vibration time is prolonged under the action of the spring elastic force, so that the gas inside the airway 41 is drawn out during the reciprocating motion of the exhaust electric one-way valve; thereby, the inside of the airway 41 is in a negative pressure state, so that the deformation section 45 is depressed downward to form a suction cup shape, and since the air in the gap between the bottom of multiple marble slabs and the horizontal pads has been emptied, the suction cup firmly adsorbs the bottom of the marble slab, so that the marble slab will not slide relative to the horizontal pads during transportation; and, when there is more vibration during transportation, the first piston can draw out more gas under the action of vibration, so that the negative pressure inside the airway 41 is higher, the suction cup is more depressed downward, and the suction force of the suction cup formed by the deformation section 45 is greater, thereby improving the stability of the marble bottom during transportation.

[0046] After the marble slab is transferred to the right place, the handle 56 is rotated to rotate the cover plate 57 so that the second air hole of the cover plate 57 overlaps with the first air hole of the fixed plate 58, and the external air enters the air passage 41, so that the air passage 41 returns to atmospheric pressure, thereby facilitating the marble slab to be removed from the transfer vehicle. After removal, the handle 56 is rotated again so that the cover plate 57 covers the first air hole of the fixed plate 58.

[0047] The pressure-stabilizing valve 50 adopts an adjustable pressure-stabilizing valve 50, and the ventilation pressure of the pressure-stabilizing valve 50 can be adjusted. When the horizontal pad is used many times and is squeezed and deformed so that the buffering effect is weakened, the rotating handle 56 can be pushed to the left by the foot, and the rotating handle 56 returns to its original position under the elastic force of the second spring 54, and reciprocates multiple times, thereby inflating the air channel 41 through the air intake one-way valve on the second piston 52, so that the air pressure in the air channel 41 increases, so that the flexible layer 40 and the air channel 41 form a structure similar to an airbag, which props up the flexible layer 40, thereby ensuring the buffering effect of the horizontal pad during the marble transportation process.

[0048] The above are only the embodiments of the present utility model, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
