[0004] To solve the above technical problems, the utility model adopts the technical scheme that:

[0005] A gear rack type lifting equipment front end bearing oil injection extension device, including the sleeve, the sleeve one end is connected with the first oil injection nozzle on the corresponding bearing end cover, the other end is connected with the oil pipe, a plurality of oil pipes are parallelled and led out and are fixed through a plurality of groups of oil pipe single pipe clamps, each group of oil pipe single pipe clamp can be detachably installed on the support of the fixed pile frame, the input end of each group of oil pipe is connected with the second oil injection nozzle through the oil injection nozzle connector, and the second oil injection nozzle is arranged at a position convenient for operation.

[0006] A plurality of second oil injection nozzles are arranged in a centralized manner.

[0007] The support is processed from angle steel and includes vertical angle steel and horizontal angle steel, the lower end of the vertical angle steel is welded with the fixed pile frame, and the upper end is welded and fixed with the horizontal angle steel.

[0008] The oil pipe single pipe clamp includes a lower pipe clamp and an upper pipe clamp, and the lower pipe clamp and the upper pipe clamp are screwed through bolts and form a locking hole through which the oil pipe passes.

[0009] The utility model provides a gear rack type lifting equipment front end bearing oil injection extension device, which has the following technical effects:

[0010] 1) By extending the oil injection port of the front cover of the lifting equipment to a convenient position below through the oil injection pipeline, the safety problems of workers when performing oil injection operations at height are avoided. At the same time, the oil injection ports in the same row are concentrated in one place, which effectively reduces the labor intensity of the workers and improves the oil injection efficiency.

[0011] 2) By using supports, the vertical angle steel section of the supports is welded to the surface of the fixed pile frame, reducing the impact of welding on the surface of the fixed pile frame. The oil pipe single clamp is fixed to the right angle side of the angle steel by bolts, which facilitates the replacement and maintenance of the oil pipe in the future.

[0012] The single pipe clamp consists of two steel plates on the top and bottom, and two polymer materials in the middle. The clamping force comes from the bolt fastening, so a support 7 is needed to give the single pipe clamp a certain space to install the bolt. Attached Figure Description
