Embodiment 1

[0052] The clamping part is a clamp 30, and the clamp 30 includes a left half clamp 301 and a right half clamp 302 which can be detachably connected. The groove 303 of the connecting rod end, such as figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 , Figure 9 , Figure 10 and Figure 11 shown.

[0053] The clamping part is a clamp 30, and the clamp 30 includes a left half clamp 301 and a right half clamp 302, and the inner sides of the left half clamp 301 and the right half clamp 302 are provided with grooves 303, and the grooves 303 and the concrete The connecting rod end of the piston 2 is suitable for clamping the concrete piston. When the clamp 30 is assembled with the concrete piston, it is only necessary to clamp the groove 303 of the left half clamp 301 and the right half clamp 302 to the concrete piston 2. At the end of the connecting rod, just connect the left half clamp 301 and the right half clamp 302. The clamp 30 is connected relatively firmly, and...

Embodiment 2

[0057] Embodiment 2 (not shown in the figure)

[0058] The difference from Embodiment 1 is that one end of the left half clamp 301 and one end of the right half clamp 302 are hinged to each other, and the other end of the left half clamp 301 and the other end of the right half clamp 302 are connected by bolts .

[0059] One end of the left half clamp 301 and the right half clamp 302 is hinged by a hinge, so the left half clamp 301 and the right half clamp 302 can rotate relatively, and the other ends are connected by bolts, the left half clamp 301, the right half clamp When the hoop 302 is assembled with the concrete piston, the left half hoop 301 and the right half hoop 302 do not need to be repeatedly connected through the hinged end, and the connecting rod end of the concrete piston 2 only needs to be placed on the left half hoop 301 and the right half hoop 301. In the groove 303 of the half clamp 302, the other end can be fixedly connected by bolts, which further improves...

Embodiment 3

[0062] Embodiment three (not shown in the figure)

[0063] The difference from Embodiment 1 and Embodiment 2 is that the concrete piston connector includes a mounting plate and a plurality of movable grapples arranged on the mounting plate, and the multiple movable grapples are distributed at intervals along the circumferential direction of the mounting plate.

[0064] The concrete piston connector includes a mounting plate and multiple movable grapples. The multiple movable grapples are all facing the concrete piston and can be hooked with the connecting rod end of the concrete piston 2 to play the role of multi-point limit. The movable grapples are arranged on the installation plate and distributed at intervals along the circumferential direction of the installation plate, so that multiple movable grapples can be hooked at multiple points along the circumferential direction of the concrete piston, effectively improving the reliability of the connection between the movable gra...

Abstract

The invention provides a concrete piston dismounting and mounting tool. The tool comprises a supporting base, a push-pull rod and a concrete piston connecting piece, wherein one end of the push-pull rod is hinged to the supporting base, one end of the concrete piston connecting piece is rotatably connected with the middle of the push-pull rod and can be slidably connected in the length direction of the push-pull rod, and the other end of the concrete piston connecting piece is provided with a clamping part which can be detachably clamped with the connecting rod end of a concrete piston. According to the concrete piston dismounting and mounting tool, not only the structure is simple, assembling is convenient, but also the tool can be suitable for concrete pistons in different structural forms, meanwhile, other power sources are not needed, the mounting and dismounting of the concrete piston can be completed in a manual mode, therefore outage operation can be realized, and potential safety hazards caused by misoperation when the concrete piston is dismounted and mounted do not exist.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to a disassembly and assembly tool for concrete pistons. Background technique [0002] At present, the concrete conveying equipment drives the concrete piston to reciprocate in the conveying cylinder through the main oil cylinder to realize the suction and delivery of concrete. The concrete piston is a vulnerable part, so it needs to be replaced frequently. At present, some concrete pump trucks on the market are equipped with the function of automatically withdrawing the piston, but due to cost and space considerations, some pump trucks are not equipped with this function, so the concrete piston must be removed manually. Contents of the invention [0003] In order to solve at least one of the above technical problems, the object of the present invention is to provide a concrete piston disassembly tool. [0004] In order to achieve the above object, the tech...
