Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated trolleys, in particular to a prefabricated component assembly trolley. Background Art

[0002] In the process of assembling prefabricated parts using an assembly trolley, the assembly trolley will be subjected to a reaction force while squeezing the prefabricated parts. Usually, the assembly trolley is parked entirely by the friction between the wheels and the track, and the friction between the brake structure and the track. Once a large reverse force is applied during the assembly of prefabricated parts, the existing friction force is difficult to overcome the reaction force generated by the assembly operation, resulting in a slip. Utility Model Content

[0003] The utility model aims to provide a prefabricated component assembly trolley, which improves the operation stability of the assembly trolley by increasing the squeezing force between the rail clamp and the tread of the rail.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A prefabricated parts assembly trolley, with steel rails fixed on the ground, comprising a chassis, wheels installed at the lower part of the chassis, a trolley frame arranged at the upper end of the chassis, and an assembly trolley installed at the top of the trolley frame; the wheels move along the steel rails;

[0006] The rail clamp comprises a guide rod, two clamping plates are relatively mounted on the guide rod, a waist-shaped hole is provided at the upper end of the clamping plate, a pin shaft is passed through the waist-shaped hole, and the two ends of the pin shaft are respectively connected to the bottom of the chassis; a clamping groove is provided on one side of the lower part of the clamping plate, and the two sides of the rail are respectively located in the corresponding clamping grooves; threads in opposite directions are provided in the two clamping plates, and the positive and negative thread shafts are respectively mounted in the two clamping plates by cooperating with two groups of threads in opposite directions, and a hand wheel is fixed on the ends of the positive and negative thread shafts; by turning the hand wheel to toggle the positive and negative thread shafts, the positive and negative thread shafts drive the two clamping plates to approach to clamp the rail in between;

[0007] When the assembly trolley is used to assemble prefabricated parts, the force of squeezing the prefabricated parts will cause the assembly trolley as a whole to be slightly lifted along the inclined surface of the waist-shaped hole in the clamping plate. The gravity of the assembly trolley and the gravity of the prefabricated parts will press on the two clamping plates of the rail clamp. The clamping plate is equivalent to a lever-type force amplification mechanism, which will increase the clamping force of the rail clamp and the tread of the rail in the vertical direction, thereby ensuring that the assembly trolley will not move.

[0008] Preferably, both ends of the guide rod are suspended on the chassis by springs, so that the rail clamp will not fall when not in use and can be suspended in the air, thereby ensuring convenience for the next operation.

[0009] Preferably, the assembling trolley includes a main frame. One end of the transverse movement oil cylinder is connected to the trolley frame, and the other end is connected to the main frame. The transverse movement oil cylinder expands and contracts to drive the main frame to move horizontally.

[0010] Preferably, sleeves are vertically installed at both ends of the main frame, and the precast component support frame is installed in the sleeves to lift and lower along the vertical direction; a lifting oil cylinder is vertically installed on the upper part of the main frame, and the lifting oil cylinder drives the precast component support frame to lift and lower to support the precast component.

[0011] Preferably, a longitudinal adjustment oil cylinder is installed at one end of the precast component support frame, and a longitudinal extrusion block is installed at one end of the longitudinal adjustment oil cylinder. The longitudinal adjustment oil cylinder drives the longitudinal extrusion block to extrude the precast component and the sealing strip between two precast components along the horizontal direction.

[0012] Preferably, in the length direction of the precast component support frame, the two sleeves are arranged at one end of the precast component support frame that is biased towards the longitudinal adjustment oil cylinder, so as to improve the reliability of the structure when the precast component is extruded.

[0013] The beneficial effects of the present utility model are as follows:

[0014] When using the assembling trolley to assemble precast components, the acting force generated by extruding the precast components will cause the whole assembling trolley to slightly lift along the inclined plane of the waist-shaped hole in the clamping plate. The gravity of the assembling trolley and the gravity of the precast components will press on the two clamping plates of the rail clamp. The clamping plate is equivalent to a lever-type force amplification mechanism, which will increase the vertical clamping force between the rail clamp and the tread surface of the rail (the tread surface is the top surface of the rail that contacts the rail clamp). As the clamping force increases, a greater frictional force can be generated to overcome the driving force generated by extruding the precast components, so as to ensure that the assembling trolley will not move and improve the reliability of the structure of the trolley during operation.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Refer to Figure 1 and Figure 2 , this embodiment provides a prefabricated component assembly trolley. The rail 1 is fixed on the ground and includes a chassis 4. Wheels 2 are installed at the lower part of the chassis 4. A bogie frame 5 is arranged at the upper end of the chassis 4. An assembly trolley 6 is installed at the top of the bogie frame 5. The wheels 2 move along the rail 1.

[0025] Refer to Figure 5 and Figure 6 , the rail clamp 3 includes a guide rod 34. Two splints 31 are oppositely installed on the guide rod 34. A waist-shaped hole 33 is opened at the upper end of the splint 31. A pin shaft 32 is inserted through the waist-shaped hole 33. Two ends of the pin shaft 32 are respectively connected to the bottom of the chassis 4. A clamping groove 37 is opened at one side of the lower part of the splint 31. Two sides of the rail 1 are respectively located in the corresponding clamping grooves 37. Threads with opposite directions are opened in the two splints 31. Two sets of threads with opposite directions are respectively arranged at two ends of the left and right hand thread shaft 35 to form left and right hand threads. The two sets of threads with opposite directions of the left and right hand thread shaft 35 are respectively matched with the threads in the two splints 31. Thus, two ends of the left and right hand thread shaft 35 are respectively installed in the two splints 31. A hand wheel 36 is fixed at the end of the left and right hand thread shaft 35. By rotating the hand wheel 36 to drive the left and right hand thread shaft 35, the left and right hand thread shaft 35 drives the two splints 31 to approach each other to clamp the rail 1 in the middle.

[0026] When using the assembly trolley 6 to assemble prefabricated components, the acting force generated by squeezing the prefabricated components will cause the entire assembly trolley to slightly lift along the inclined plane of the waist-shaped hole 33 in the clamping plate. The gravity of the assembly trolley and the gravity of the prefabricated components will press on the two clamping plates 31 of the rail clamp 3. The clamping plate 31 is equivalent to a lever-type force amplification mechanism, which will increase the vertical clamping force between the rail clamp 3 and the tread of the rail (the tread is the top surface of the rail that contacts the rail clamp 3). As the clamping force increases, a greater frictional force can be generated to overcome the driving force generated by squeezing the prefabricated components, thereby ensuring that the assembly trolley does not move and improving the reliability of the trolley during operation.

[0027] Both ends of the guide rod 34 are suspended on the chassis 4 through springs. When parking operation is not required, the rail clamp 3 disengages from the rail, and the spring overcomes the weight of the rail clamp 3 to suspend the rail clamp 3 in the air, so as to enable the rail clamp 3 to hover on the working surface when not in use, which is convenient for the next operation.

[0028] Refer to Figure 3 , the assembly trolley 6 includes a main frame 61. One end of the transverse movement oil cylinder 66 is connected to the trolley frame 5, and the other end is connected to the main frame 61. The transverse movement oil cylinder 66 expands and contracts to drive the main frame 61 to move horizontally, so as to push the entire assembly trolley 6 to move horizontally, and is used to adjust the horizontal position of the prefabricated components during the process of assembling the prefabricated components.

[0029] Refer to Figure 4 , sleeves 63 are vertically installed at both ends of the main frame 61. The prefabricated component support frame 64 is installed in the sleeves 63 so as to lift and lower along the vertical direction. The lifting oil cylinder 62 is vertically installed on the upper part of the main frame 61. The lifting oil cylinder 62 drives the prefabricated component support frame 64 to lift and lower to support the prefabricated components. During the process of assembling the prefabricated components, the lifting oil cylinder 62 expands and contracts along the vertical direction to drive the prefabricated component support frame 64 to lift and lower, and the prefabricated component support frame 64 drives the prefabricated components to lift and lower, so as to adjust the height of the prefabricated components.

[0030] Refer to Figure 3 , the longitudinal adjustment oil cylinder 65 is installed at one end of the prefabricated component support frame 64. The longitudinal adjustment oil cylinder 65 is used to squeeze the prefabricated components and the sealing strip between two prefabricated components along the horizontal direction.

[0031] The longitudinal adjustment oil cylinder 65 is installed at one end of the prefabricated component support frame 64. A longitudinal extrusion block 67 is installed at one end of the longitudinal adjustment oil cylinder 65. The longitudinal adjustment oil cylinder 65 expands and contracts along the horizontal direction to drive the longitudinal extrusion block 67, and the longitudinal extrusion block 67 pushes the prefabricated components to move along the horizontal direction, so as to realize the extrusion of the prefabricated components along the horizontal direction.

[0032] Refer toFigure 4 , in the length direction of the precast support frame 64, the two sleeves 63 are arranged at one end of the precast support frame 64 closer to the longitudinal adjustment oil cylinder 65, improving the reliability of the structural force when extruding the precast

[0033] during the extrusion of the precast.

[0034] Working principle:

[0035] When using the assembly trolley 6 to assemble the precast, the acting force generated by extruding the precast will cause the whole assembly trolley to slightly lift along the inclined plane of the waist-shaped hole 33 in the clamping plate. The gravity of the assembly trolley and the gravity of the precast will press on the two clamping plates 31 of the rail clamp 3. The clamping plate 31 is equivalent to a lever-type force amplification mechanism, which will increase the vertical clamping force between the rail clamp 3 and the tread of the rail (the tread is the top surface of the rail in contact with the rail clamp 3). As the clamping force increases, a greater frictional force can be generated to overcome the driving force generated by extruding the precast, thereby ensuring that the assembly trolley does not move and improving the reliability of the trolley during operation.

The scope of the present invention is defined by the appended claims and their equivalents.
