Abstract
Description
Technical Field
[0001] This utility model relates to a pin device, and in particular to a pin device for positioning the lifting block of a step-by-step lifting device. Background Technology
[0002] Currently, in the lifting equipment, the raised blocks are usually locked using a pin device when they rise. However, the locking cylinder and the pin of the current pin device are directly installed in the locking hole, and the piston rod of the locking cylinder is directly connected to the pin. In this way, when the cylinder pushes the pin into the pin groove of the raised block, the piston rod of the cylinder is not supported and is rigidly connected to the pin, which leads to unstable force. After long-term use, the piston rod will break, causing installation accidents. Utility Model Content
[0003] This utility model provides a positioning pin device for the lifting block of a step-by-step jacking device. It can increase the support effect of the pin body on the lifting block and improve the safety of lifting the lifting block.
[0004] The present invention adopts the following technical solution: a positioning pin device for raising blocks of a step-by-step lifting equipment, comprising a pin telescopic cylinder and a pin body. The shape of the pin body corresponds to the pin groove on the side of the raised block. One end of the pin telescopic cylinder is provided with a cylinder base. The pin telescopic cylinder is fixedly installed in the locking hole through the cylinder base. The piston rod inside the pin telescopic cylinder passes through the other end of the pin cylinder and is rotatably supported by the pin body. When it is necessary to lock the raised block, the pin telescopic cylinder pushes the pin body into the pin groove on the side of the raised block through the piston rod.
[0005] Furthermore, the side of the pin body is provided with a mounting groove opposite to the piston rod. A transverse support shaft is installed in the mounting groove. The piston rod extends into the mounting groove, and the transverse support shaft passes vertically through the side of the piston rod to form a rotating support connection with the piston rod. The piston rod rotates around the transverse support shaft.
[0006] Furthermore, the main body of the latch is designed as a flat block.
[0007] This utility model has the following beneficial effects: By adopting the above technical solution, the pin telescopic cylinder of this utility model pushes the pin body into the pin groove on the side of the raised block. Since the piston rod and the pin body are connected by a transverse support shaft, the transverse support shaft has both supporting and rotating functions, thus more stably supporting the raised block, distributing force more evenly, and ensuring safety during the raising block's lifting and lowering process. Furthermore, the piston rod and the pin body are rotatably connected, allowing the pin body's support angle to be adjusted by rotating it during the raising or lowering process, thereby achieving better support. The pin body of this utility model is designed as a flat block, which increases the contact area between the pin body and the bearing surface. Attached Figure Description
[0008] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.
[0009] Figure 1 This is a schematic diagram of the structure of this utility model.
[0010] Figure 2 This is a schematic diagram of the installation of the present invention and the shim block. Detailed Implementation
[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0012] exist Figure 1 This utility model provides a positioning pin device for raising blocks in a step-by-step jacking device. It includes a pin telescopic cylinder 1 and a pin body 2. The pin body 2 corresponds in shape to the pin groove 8 on the side of the raised block 7. One end of the pin telescopic cylinder 1 is provided with a cylinder base 3, and the pin telescopic cylinder 1 is fixedly installed in a locking hole via the cylinder base 3. The piston rod 4 inside the pin telescopic cylinder 1 passes through the other end of the cylinder and is rotatably supported by the pin body 2. When it is necessary to lock the raised block, the pin telescopic cylinder 1 pushes the pin body 2 into the pin groove 8 on the side of the raised block 7 via the piston rod 4. Figure 2In this embodiment, the side of the pin body 2 is provided with a mounting groove 5 opposite to the piston rod 4. A transverse support shaft 6 is installed in the mounting groove 5. The piston rod 4 extends into the mounting groove 5, and the transverse support shaft 6 passes vertically through the side of the piston rod 4 to form a rotational support connection with the piston rod 4. The piston rod 4 rotates around the transverse support shaft 6. In this embodiment, the pin body 2 is set as a flat block.
[0013] The usage process of this utility model is as follows: The pin telescopic cylinder 1 of this utility model is installed into the locking hole through the cylinder base 3. When the shim needs to be locked during the process of raising it, the pin telescopic cylinder 1 extends the pin body 2 into the pin groove 8 on the side of the shim 7 through the piston rod 4. Since the piston rod 4 and the pin body 2 are connected by the transverse support shaft 6, the transverse support shaft 6 has the functions of support and rotation, so that the shim can be supported more stably. At the same time, the support angle of the pin body 2 can be adjusted by rotating the pin body 2 during the process of raising or lowering the shim, so as to achieve a better support effect.
[0014] However, this is not the only possibility. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
