Description

Technical Field

[0001] The utility model relates to the technical field of sliding parts, in particular to a sliding part for a construction lifting platform. Background Art

[0002] Sliders for construction lifts are parts used in construction lifts. They are usually installed on the guide rails of the lifts to achieve smooth lifting and movement of the lifts. There are many types of slides for construction lifts, including rollers, sliders, and slides. These slides are usually made of high-strength materials, such as steel and aluminum alloys, to ensure that they have sufficient strength and wear resistance. Slides play a very important role in construction lifts. They can not only reduce the friction between the lift and the guide rails, improve the operating efficiency of the lift, but also ensure the stability and safety of the lift.

[0003] The existing sliding parts for construction lifting platforms will cause wear when the slider and the guide rod slide, so the slider and the guide rod need to be lubricated in time. However, manual lubrication of the sliding parts is not only inefficient, but also difficult to lubricate evenly. Therefore, it is necessary to redesign a sliding part for construction lifting platforms to address the above problems. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and proposes a sliding member for a construction lifting platform.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sliding part for a construction lifting platform comprises two mounting plates, which are fixedly connected by two fixing plates, and a plurality of protrusions are vertically fixedly installed on one side of each fixing plate. A guide rod is fixedly connected between the two mounting plates. A sliding block is sleeved on the outer wall of the guide rod, a sliding groove is provided on the sliding block, and the outer wall of the guide rod contacts the inner wall of the sliding groove, a lubrication groove is provided on the inner wall of the sliding groove, and two working cavities are symmetrically provided in the sliding block, each of the working cavities is provided with a pushing device, and the output end of each pushing device is abutted against a protrusion corresponding to the position, and a conveying groove is provided on the inner side wall of each working cavity, and the conveying groove is connected to the lubrication groove.

[0007] Preferably, each of the pushing devices includes a spring, and the spring is fixedly connected to the inner wall of the working chamber, one end of the spring is fixedly connected to a piston, and the piston is slidably clamped in the working chamber, and a fixing rod is fixedly installed at one end of the piston away from the spring, and one end of the fixing rod is against a corresponding protrusion in the position.

[0008] Preferably, one end of each fixing rod away from the piston is rounded.

[0009] Preferably, the protruding end of each of the protrusions is rounded.

[0010] Preferably, a semipermeable membrane is provided on the inner wall of each conveying trough.

[0011] Preferably, a one-way pipe is provided on the top wall of each working cavity, and one end of each one-way pipe passes through the working cavity at the corresponding position and extends outward.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting a slider, a pushing device, a convex block, and a conveying groove, they cooperate with each other. The movement of the slider can make the fixed rod of the pushing device abut against the convex block. The abutment between the convex block and the fixed rod can push the lubricating oil in the working chamber into the lubrication groove, thereby achieving real-time lubrication between the guide rod and the slider.

[0014] 2. By setting a semipermeable membrane, the lubricating oil can be evenly infiltrated into the lubricating groove by the semipermeable membrane, so as to prevent the lubricating oil in the working chamber from being transported to the lubricating groove by the driven device in large quantities at one time, resulting in waste of lubricating oil.

[0015] In summary, the utility model provides a slider, a pushing device, a bump, a conveying groove, and a semipermeable membrane. By utilizing the cooperation between the conveying device and the semipermeable membrane, the lubricating oil in the working chamber can be evenly infiltrated into the lubrication groove through the semipermeable membrane, thereby achieving real-time and even lubrication between the guide rod and the slider.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A sliding member for a construction lifting platform comprises two mounting plates 1, which are fixedly connected by two fixing plates 2, a plurality of protrusions 3 are vertically fixedly installed on one side of each fixing plate 2, a guide rod 4 is fixedly connected between the two mounting plates 1, a slider 6 is sleeved on the outer wall of the guide rod 4, a slide groove 7 is provided on the slider 6, and the outer wall of the guide rod 4 contacts the inner wall of the slide groove 7, a lubrication groove 8 is provided on the inner wall of the slide groove 7, two working chambers 12 are symmetrically provided in the slider 6, a pushing device is provided in each working chamber 12, and the output end of each pushing device is against the protrusion 3 corresponding to the position, a conveying groove 9 is provided on the inner side wall of each working chamber 12, and the conveying groove 9 is connected with the lubrication groove 8.

[0022] Each pushing device includes a spring 13, and the spring 13 is fixedly connected to the inner wall of the working chamber 12. One end of the spring 13 is fixedly connected to the piston 11, and the piston 11 is slidably clamped in the working chamber 12. A fixing rod 5 is fixedly installed on the end of the piston 11 away from the spring 13, and one end of the fixing rod 5 is abutted against the corresponding protrusion 3 in the position. By abutting one end of the fixing rod 5 against the protrusion 3, the fixing rod 5 can compress the spring 13 through the piston 11, and at the same time, the lubricating oil in the working chamber 12 can be pushed into the conveying groove 9.

[0023] One end of each fixing rod 5 away from the piston 11 is rounded. It should be noted that this design allows the fixing rod 5 to pass through the raised end of the bump 3 better.

[0024] The raised end of each protrusion 3 is rounded. It should be noted that such a design allows the fixing rod 5 to pass through the raised end of the protrusion 3 more easily.

[0025] A semipermeable membrane 14 is provided on the inner wall of each conveying groove 9 . It should be noted that the semipermeable membrane 14 can effectively penetrate the lubricating oil to prevent the lubricating oil from passing through the conveying groove 9 in large quantities at one time.

[0026] A one-way pipe 10 is provided on the top wall of each working chamber 12, and one end of each one-way pipe 10 passes through the corresponding working chamber 12 and extends outward. It should be noted that the lubricating liquid can only be transported into the working chamber 12 through the one-way pipe 10, and the lubricating liquid cannot be discharged from the outside through the one-way pipe 10.

[0027] When the utility model is in use, firstly, lubricating oil can be added into the working chamber 12 through the one-way pipe 10. When the slider 6 moves, one end of the fixed rod 5 will abut against the protrusion 3. As the slider 6 moves, the fixed rod 5 will abut against the raised end of the protrusion 3. At this time, the fixed rod 5 will drive the piston 11 to move in the working chamber 12. Then, the piston 11 will transport the lubricating oil inside the working chamber 12 through the semipermeable membrane 14 and the conveying groove 9 to the lubricating groove 8. When the lubricating groove 8 is filled with lubricating oil, the lubricating oil can lubricate the outer wall of the guide rod 4, and there is no need to manually lubricate the guide rod 4 and the slider 6, which effectively reduces the wear between the guide rod 4 and the slider 6.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
