Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The embodiment is as follows:
as shown in fig. 1-3, a pallet truck with a damping function comprises a pallet truck body 1, wherein forks 3 with built-in damping assemblies 2 are symmetrically arranged on the pallet truck body 1, and a travelling wheel 4 is hinged to one end, away from the pallet truck body 1, of each fork 3. Through set up damping subassembly 2 in fork 3 inside, alleviate the impact that the road surface brought, absorb the vibration that produces when jolting, improve the holistic anti vibration performance of carrier, stability when improving article transport.
The pallet fork 3 comprises an installation seat 5 and a loading bedplate 6, the installation seat 5 is connected with the pallet body 1, the loading bedplate 6 covers the installation seat 5, the installation seat 5 and the loading bedplate are combined to form an internal cavity, and the damping assembly 2 is located in the cavity and connected with the installation seat 5 and the loading bedplate 6. The structure can effectively prevent dust by arranging the damping component 2 inside, and the stability can be improved by the buffer action of the damping component 2 when articles are placed on the load bedplate 6.
The vibration damping assembly 2 comprises a plurality of vibration damping dampers 7, the vibration damping dampers 7 inside each fork 3 are arranged in double rows along the movement direction of the fork 3, and each row comprises at least two vibration damping dampers 7. A plurality of damping dampers 7 rationally set up in fork 3, can make the article on each position of fork 3 can both receive the damping effect, improve stability.
The vibration reduction damper 7 comprises a base 71 fixedly connected on the mounting seat 5 and a damping seat 72 fixedly connected with the load bedplate 6, the base 71 and the damping seat 72 are connected through a compression spring 73, the compression spring 73 is sleeved on the periphery of the base 71, a movable cavity is arranged in the middle of the base 71, and a piston rod 79 on the damping seat 72 is inserted in the movable cavity and moves up and down along the inner wall of the base 71 under the action of external force; the movable cavity is also internally provided with a damping part 74, the damping part 74 is annularly arranged at the periphery of the piston rod 79, the damping part 74 is filled with silicon oil, the piston rod 79 is provided with a contact element 75, the contact element 75 is positioned in the middle of the silicon oil to divide the damping part 74 into an upper cavity 76 and a lower cavity 77, and the contact element 75 is provided with a circulating hole 78 for enabling the silicon oil in the upper cavity 76 and the lower cavity 77 to flow. Because the carrier needs to bear a large mass of articles, the effect of damping by using a spring is not obvious, the damping effect can be further improved by combining the silicone oil damping part 74, the silicone oil has compression elasticity and can be suitable for the condition of strong mechanical vibration, when a road surface bump is encountered, the base 71 moves upwards relative to the damping seat 72, the space of the silicone oil in the lower cavity 77 becomes smaller and the contact element 75 can be pressed upwards, the lower part of the upper cavity 76 has a redundant space, but the silicone oil pressed in the lower cavity 77 can not be directly transferred to the redundant space due to the blocking of the contact element 75 and can only be slowly transferred through the circulation hole 78, so that the moving speed of the base 71 relative to the damping seat 72 is reduced, and the damping effect is generated.
The two rows of damper 7 are separated by a link 8 inside each fork 3. Not only can help to support the vibration-damping dampers 7, but also can avoid the mutual collision between the two rows of vibration-damping dampers 7.
At least two road wheels 4 are provided on each fork. Can share bearing pressure, prolong the life of every walking wheel 4.
