Description

Technical Field

[0001] This utility model relates to an auxiliary device for adding lubricating oil to wire ropes, specifically a self-lubricating device for wire ropes of fixed winch gate openers. Background Technology

[0002] In heavy machinery such as hoists and gate openers, wire ropes are key transmission and load-bearing components. Their lubrication status directly affects the safety, efficiency and service life of the equipment. Therefore, it is necessary to coat the surface of the wire rope with lubricating oil. In the existing technology, the lubricating oil is usually applied to the wire rope manually. This existing operation method usually has the following problems: (1) In order to ensure operational safety, lubrication must usually be carried out when the equipment is stopped, which affects the continuity of production and work efficiency. (2) Manual application makes it difficult to ensure that the lubricating oil is evenly distributed throughout the entire length of the wire rope and the gap between the strands, resulting in local dry friction or over-lubrication. (3) Frequent manual intervention increases labor costs and poses safety hazards when working at height or in confined spaces. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a time-saving, labor-saving, lubricating, uniform, and efficient self-lubricating device for the wire rope of a fixed winch gate opener.

[0004] To solve the above-mentioned technical problems, the present invention provides a self-lubricating device for the wire rope of a fixed winch gate opener, comprising a support assembly fixedly installed above the guide wheel of the wire rope, and at least one lubrication assembly consisting of an oil cylinder, an oil delivery frame installed at the bottom of the oil cylinder, a push plate installed inside the oil cylinder capable of reciprocating up and down inside the oil cylinder, and a push rod for pushing the push plate. Each oil delivery frame in the lubrication assembly has an oil outlet hole communicating with the inner cavity of the oil cylinder. Each lubrication assembly is fixedly installed on the support assembly with the oil outlet hole of the oil delivery frame facing the guide groove of the guide wheel. The bottom of the oil delivery frame in each lubrication assembly is also provided with an oil baffle plate that cooperates with the guide groove of the guide wheel. By pushing the push rod, the lubricating oil in the oil cylinder can be output through the oil outlet hole of the oil delivery frame and coated onto the wire rope wound in the guide groove of the guide wheel after being blocked by the oil baffle plate.

[0005] The support assembly includes a support plate fixedly mounted on a support seat of the guide wheel and a top plate mounted on the support plate, and the oil cylinders of the refueling assembly are all fixedly mounted on the top plate.

[0006] The top open end of the oil cylinder in the refueling assembly is fixedly installed with a horizontal bracket having a central hole, and the push rod extends out of the oil cylinder through the central hole.

[0007] The outer circumferential surface of the push plate is provided with an annular groove, and a sealing ring is placed in the annular groove.

[0008] Two symmetrically arranged fixing blocks are welded to the top edge of the oil drum, and the two ends of the horizontal support are fixedly installed on the two fixing blocks by fasteners.

[0009] Each of the aforementioned oil delivery frames is equipped with two oil outlet holes.

[0010] Each of the oil delivery frames is provided with two oil baffles at its bottom. The cross-sectional shape of the oil baffles is a trapezoidal structure adapted to the cross-section of the guide groove of the guide wheel. The two oil baffles of each oil delivery frame are arranged symmetrically along the center line of the guide wheel.

[0011] An operating handwheel is installed at the top of the push rod.

[0012] A pair of pull rings are provided on the top surface of the oil baffle.

[0013] A reinforcing plate is provided between the support plate and the top plate.

[0014] The center hole of the horizontal support is a threaded hole, and the push rod is provided with an external thread that mates with the threaded hole. By operating the operating handwheel, the push rod can be rotated relative to the horizontal support, thereby driving the push plate to move up and down reciprocally.

[0015] The advantages of this utility model are: (1) By setting up an oiling component supported above the guide wheel of the wire rope by a support component, the lubricating oil in the oil cylinder can be directly applied to the wire rope wound in the guide groove of the guide wheel by pushing the push rod during the operation of the equipment. There is no need to stop the machine for lubrication, which ensures the continuity of production and work efficiency. At the same time, since the coating operation is carried out during the operation of the equipment, the lubricating oil can be evenly distributed throughout the entire length of the wire rope and the strand gap (the lubrication process is continuous and uniform), avoiding the problems of local dry friction or over-lubrication. In addition, it is easy to operate and implement, with low labor costs and avoids safety hazards during operation. This technology can not only significantly extend the service life of the wire rope, but also reduce maintenance costs and safety risks.

[0016] (2) By setting oil baffles at the bottom of the oil delivery rack in each refueling assembly, which are in sync with the guide groove of the guide wheel, the lubricating oil can be concentrated and slowly coated, preventing the lubricating oil from deviating from the lubrication area, and further ensuring the uniformity of lubrication.

[0017] (3) By fixing a horizontal bracket with a central hole at the top open end of the oil cylinder in the refueling assembly, the push rod can be extended out of the oil cylinder through the central hole, which facilitates the stability of operation. Attached Figure Description

[0019] The following detailed description of the self-lubricating device for the wire rope of the fixed winch gate opener of this utility model, in conjunction with the accompanying drawings and specific embodiments, will be provided in further detail. Example 1

[0020] like Figure 1-6 As shown, the self-lubricating device for the wire rope of the fixed winch gate opener in this embodiment is designed with the wire rope 19 wound around two side-by-side guide wheels 1 as the lubrication target. Figure 5 As can be seen, the guide wheel 1 has a guide groove 20 for the wire rope 19 to pass through. Two guide wheels 1 are mounted on a support base 22 via a support shaft 21. The wire rope 19 is guided by the guide wheels 1. Specifically, the device includes a support assembly 2 fixedly mounted above the guide wheels 1 for the wire rope 19 to pass through, and two lubrication assemblies mounted on top of the support assembly. Figure 1 As can be seen, the support assembly 2 includes two support plates 8, each fixedly mounted on a connecting plate 16 to two support seats 22 of the guide wheel, and a top plate 9 mounted on top of the two support plates. The oil cylinders 3 of both refueling assemblies are fixedly mounted on the top plate and correspond to the positions of one of the guide wheels, respectively. Figure 3 As can be seen, each refueling assembly consists of an oil cylinder 3, an oil delivery frame 6 at the bottom of the oil cylinder 3, a push plate 4 that can reciprocate up and down inside the oil cylinder, and a push rod 5 for pushing the push plate. Each oil delivery frame in the refueling assembly has an oil outlet 18 that communicates with the inner cavity of the oil cylinder. In this embodiment, each oil delivery frame 6 has two oil outlets 18. The oil cylinder 3 can be a hollow cylinder with open bottom and top, or a cylinder with only an open top. When the bottom of the oil cylinder 3 is open, it is directly fixed to the top plate, using the top plate as the bottom plate of the oil cylinder. This allows the oil cylinder to be fixed to the top plate, and the oil outlet of the oil delivery frame to face the guide groove of the guide wheel. Each oil delivery frame 6 in the refueling assembly also has an oil baffle 7 at its bottom that mates with the guide groove of the guide wheel. Figure 4 As shown in this embodiment, each oil delivery frame 6 is provided with two oil baffles 7 at its bottom. The cross-sectional shape of the oil baffles is a trapezoidal structure adapted to the cross-section of the guide groove of the guide wheel. The two oil baffles of each oil delivery frame 6 are symmetrically arranged along the vertical center line of the guide wheel. By pushing the push rod 5, the lubricating oil in the oil cylinder can be output through the oil outlet of the oil delivery frame and coated on the wire rope wound in the guide groove of the guide wheel by the obstruction of the oil baffles.

[0021] Furthermore, in order to ensure the sealing between the push plate and the oil cylinder and prevent the lubricating oil from being squeezed out in the reverse direction, an annular groove can be provided on the outer circumferential surface of the push plate 4, and a sealing ring 11 can be placed in the annular groove. At the same time, in order to ensure the stability and reliability of use, a horizontal bracket 10 with a central hole can be fixedly installed at the top open end of the oil cylinder 3 in the refueling assembly. The push rod 5 extends out of the oil cylinder through the central hole, and an operating handwheel 13 is installed at the top of the push rod 5.

[0022] Furthermore, two symmetrically arranged fixing blocks 12 (at 180° angles) can be welded to the top edge of the oil drum 3. The two ends of the horizontal support 10 are fixedly installed on the two fixing blocks by fasteners, which facilitates the installation of the horizontal support.

[0023] Furthermore, to improve ease of operation, the center hole of the horizontal support 10 can be configured as a threaded hole, and the push rod 5 can be provided with an external thread that mates with the threaded hole. By operating the handwheel 13, the push rod 5 can be rotated relative to the horizontal support 10, thereby driving the push plate 4 to reciprocate up and down. Figure 3 As can be seen, the operating handwheel 13 and the push rod 5 are relatively fixed, while the push rod 5 and the horizontal support 10 are connected by a thread. At this time, the push rod 5 can be rotated by manually turning the operating handwheel 13. The push rod 5 then moves up and down reciprocally through the rotation of the operating handwheel 13. Thus, the up and down movement of the push rod 5 can drive the push plate 4 to move up and down reciprocally. When the push plate 4 moves down, it can inject lubricating grease. The lubricating grease is evenly applied to the surface of the wire rope through the oil delivery frame 6. This method is labor-saving and reliable.

[0024] In addition, a pair of pull rings 14 can be provided on the top surface of the oil baffle 7 to facilitate the installation and removal of the oil baffle. A reinforcing plate 15 can also be provided between the support plate 8 and the top plate 9 to improve the stability of the entire support assembly. Of course, in order to ensure the reliability of the installation between the oil transfer frame 6 and the top plate, a stiffening plate 17 can be installed between the top of the oil transfer frame 6 and the bottom surface of the top plate. Example 2

[0025] The self-lubricating device for the wire rope of the fixed winch gate opener in this embodiment is largely the same as that in Embodiment 1. The difference is that it is used in scenarios where there is only one guide wheel. Of course, in this case, it is only necessary to install a lubrication component on the support assembly that corresponds to the position of the guide wheel.

[0026] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
