Description

Technical Field

[0001] This invention relates to the field of wall panel transfer technology, specifically to a wall panel transfer vehicle for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to a method where wall panels needed for building construction are prefabricated in a factory according to dimensions. After prefabrication, the prefabricated panels are transported to the construction site for assembly, thereby improving construction efficiency. Currently, when building wall panels are transported to the construction site by trucks, the large size of the trucks often results in the panels being piled up in an empty area. Then, depending on the construction location, transfer vehicles are used to move the panels to the next location. Therefore, transfer vehicles are essential at the construction site to reduce the workload of workers. Current transfer vehicles use a clamping mechanism at the top of the transport unit to clamp the wall panels, and then the entire transport unit moves left and right on the bottom wheels to achieve the transfer effect (see application number).

[0003] CN201710408269.7 discloses an indoor large wall panel installation machine, belonging to the field of building equipment. It includes a movable base assembly, a wall panel clamping mechanism hinged to the front end of the base assembly, and a tilt angle adjustment mechanism that drives the wall panel clamping mechanism to tilt around a horizontal axis. The base assembly includes a base sleeve and a base core disposed within the base sleeve, which extends and retracts under the drive of a translation mechanism. The lower end of the wall panel clamping mechanism is provided with a load-bearing claw for placing the wall panel, and the upper end of the wall panel clamping mechanism is provided with an upper clamping claw corresponding to the load-bearing claw, which moves up and down along the wall panel clamping mechanism under the drive of a clamping mechanism for clamping the wall panel. This invention facilitates the handling of large indoor wall panels and precisely controls the installation position of the wall panels.

[0004] 1. However, the aforementioned transfer vehicles cannot adequately ensure the safety of the wall panels during the transfer process. Typical transfer vehicles simply clamp the two ends of the wall panels using a clamping mechanism, achieving a clamping effect. However, when only one clamping mechanism is used, it frequently malfunctions, causing the wall panels to fall and become damaged. This results in damage to the entire wall panel during transportation, increasing construction costs. Summary of the Invention

[0005] The purpose of this invention is to provide a wall panel transfer vehicle for prefabricated buildings, addressing the shortcomings of existing transfer vehicles on the market, which fail to adequately protect the safety of wall panels during transfer. Typical transfer vehicles simply clamp the ends of the wall panels using a single clamping mechanism. While this achieves a clamping effect, relying on only one mechanism often leads to malfunctions, resulting in wall panels falling and becoming damaged during transport, thus increasing construction costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wall panel transfer vehicle for prefabricated buildings, comprising a transfer body with movable rollers at its bottom;

[0007] The first telescopic cylinder is located on the upper right side of the transfer body, and its bottom is connected to the transfer body by a shaft.

[0008] The lifting mechanism, located on the right side of the transfer body, is also connected to the bottom of the transfer body via a shaft.

[0009] Also includes

[0010] The double clamping mechanism, located in the middle of the lifting mechanism, is used to clamp the wall panel.

[0011] Preferably, the lifting mechanism includes:

[0012] The fixed outer shell has two parts, which are fixed at the top of the transfer body, and the interior of the fixed outer shell is a hollow structure.

[0013] The lead screw is located at the back of the fixed housing, and the first motor is coaxially connected to its bottom;

[0014] The lead screw is externally threaded with a rotating sleeve, and the top of the rotating sleeve is connected to a double clamping mechanism.

[0015] Preferably, the dual clamping mechanism includes:

[0016] The intermediate mechanism is integrally installed with the outer rotating sleeve of the lead screw;

[0017] The clamping body is connected to the intermediate mechanism via a second telescopic cylinder;

[0018] The movable rod forms a movable structure in the middle of the intermediate mechanism, and the top of the movable rod is connected to an intermediate plate, which is located in the middle position of the intermediate mechanism.

[0019] Preferably, the intermediate mechanism includes an intermediate seat and a reserved slot, and a second telescopic cylinder is provided on the outside of the intermediate seat, and a triggering mechanism is provided inside the intermediate seat, and a moving rod is provided inside the reserved slot.

[0020] Preferably, the clamping body includes:

[0021] The clamping plate moves in the middle of the limiting plate under the action of the second telescopic cylinder, and the clamping plates moving in opposite directions form the first left and right clamping mechanism. The clamping plate is provided with a limit pin on its outside.

[0022] The sliding rod is located outside the clamping plate and is engaged in the sliding groove opened in the limiting plate;

[0023] The storage slot is located at the front end of the clamping plate, and a movable locking mechanism is engaged inside the storage slot.

[0024] The cable channel runs through the middle seat and the storage slot.

[0025] The locking mechanism includes:

[0026] The movable base moves inside the storage slot and has pin holes evenly distributed on its exterior.

[0027] The second motor is located inside the movable base. The top of the second motor is connected to the locking head via a rotating shaft, and the locking head is arranged in an "L" shape.

[0028] The pull wire has one end connected to the tail of the movable seat, and the other end passes through the wire groove and is connected to the triggering mechanism.

[0029] Preferably, the movable rod has teeth evenly distributed on its outer side, and the movable rod is used to trigger the triggering mechanism to work.

[0030] Preferably, the triggering mechanism includes:

[0031] The meshing gear meshes with the toothed block outside the moving rod, and the meshing gear is coaxially connected to the outside of the first bevel gear. The outside of the first bevel gear is coaxially connected to the second bevel gear, and the second bevel gear is coaxial with the winding roller. The other end of the pull wire is wound on the winding roller.

[0032] Compared with the prior art, the beneficial effects of the present invention are: when transporting wall panels, the wall panel transfer vehicle of the prefabricated building can perform double clamping work on the wall panels, making the entire transport vehicle safer during transportation.

[0033] 1. The double clamping mechanism consists of two parts: First, the two clamping plates can be moved towards each other by the second telescopic cylinder 5. This movement of the two clamping plates provides the first clamping of the wall panel. Simultaneously, when the wall panel moves towards the middle mechanism, the middle plate is triggered. As the middle plate moves towards the middle mechanism, the triggering mechanism further clamps the entire locking mechanism towards the middle mechanism, achieving a further clamping effect on the wall panel. This ensures that even if the second telescopic cylinder malfunctions or an accident occurs during the transfer, the transfer vehicle can still perform the wall panel clamping operation normally, guaranteeing efficient transfer.

[0034] 2. When the triggering mechanism is working, it completes the second limiting clamping work by pressing the middle plate with the wall plate. Therefore, when the transfer vehicle transfers the wall plate, the operation steps are the same as those of the existing transfer vehicles on the market. No extra operation is required from the staff to achieve the double clamping effect, which is very convenient to use. Attached Figure Description

[0062] The slide rod 62 is located outside the clamping plate 61 and is engaged in the slide groove opened in the limiting plate 7;

[0063] The storage slot 63 is located at the front end of the clamping plate 61, and the storage slot 63 is fitted with a movable locking mechanism 8.

[0064] The cable channel 64 passes through the intermediate seat 41 and the storage slot 63;

[0065] Specifically, the first stage of reinforcement work is carried out on the wall panels.

[0066] Locking mechanism 8 includes:

[0067] The movable seat 81 moves inside the storage slot 63 and has pin holes evenly distributed on its exterior.

[0068] The second motor 82 is located inside the movable base 81. The top of the second motor 82 is connected to the locking head 84 via a rotating shaft 83, and the locking head 84 is arranged in an "L" shape.

[0069] The pull wire 85 has one end connected to the tail of the movable seat 81, and the other end passes through the wire groove 64 and is connected to the trigger mechanism 11.

The other end of the pull wire 85 is wound on the winding roller 113.

[0074] Specifically, this enables the wall panel to control the entire triggering mechanism 11 to start working.

[0075] Working principle: When using the wall panel transfer vehicle for this prefabricated building, firstly, the entire transfer body 1 is moved to the position of the appropriate wall panel using the wheels at the bottom, and then the wall panel can be clamped and transferred.

[0076] During clamping, firstly, the second telescopic cylinder 5 is controlled to move the clamping plate 61 outwards. Then, the wall panel to be transferred is moved to the middle of the locking mechanism 8, without contacting the middle plate 10. At this point, the second telescopic cylinder 5 is controlled to move in the opposite direction, causing the clamping body 6 at its top to move in the opposite direction. When the top of the locking mechanism 8 at the top of the clamping body 6 overlaps with the wall panel, the entire transfer body 1 is pushed towards the wall panel. During this movement, since the wall panel is fixed in position, the moving rod 9 on the outside of the middle plate 10 in contact with the wall panel moves into the reserved groove 42. When the moving rod 9 moves into the reserved groove 42, the evenly distributed teeth on its outside mesh with the meshing gear 111 on the trigger mechanism 11, causing the meshing gear 111 to rotate. This causes the first bevel gear 112, which is coaxially connected to it, to rotate. The first bevel gear 112 rotates, causing the second bevel gear 114, which meshes with it, to also rotate. When the second bevel gear 114 rotates, the winding roller 113, which is coaxially connected with it, takes in the wire 85. This causes the top of the wire 85 to pull the bottom of the moving seat 81, making the moving seat 81 slide inside the storage groove 63. This causes the locking head 84 at its top to continuously press against the wall panel to complete the clamping work. When it reaches the top position, the operator needs to engage the limit pin on the clamping plate 61 with the pin hole on the moving seat 81 to fix the position of the locking mechanism 8. After fixing, the second telescopic cylinder 5 is started again, causing the two clamping plates 61 to slide left and right on the slide rod 62 to complete the clamping work on both sides of the wall panel. After that, the wall panel can be lifted and transported.

[0077] During transportation, the first motor 33 needs to be started, which drives the lead screw 32 at its top to rotate. This causes the rotating sleeve on the lead screw 32 to connect with the lead screw 32, driving the entire intermediate mechanism 4 to rise and complete the lifting operation. Then, the entire transfer body 1 is controlled to move, and the wall panel can be transferred. If it is necessary to control the angle of the wall panel during the transfer, it is only necessary to start the first telescopic cylinder 2 to complete the angle change of the wall panel. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
