Description

Technical Field

[0001] The invention relates to the technical field of supporting shaft production, and in particular to a supporting shaft production device for mining. Background Art

[0002] Mining support shafts are key components in mining equipment, and their quality and performance directly affect the stability and safety of mining equipment. Therefore, improving the manufacturing process level of mining support shafts is of great significance to ensure the normal operation of mining equipment.

[0003] The production process of supporting shafts includes material preparation, blank forging, heat treatment and tempering, semi-finishing, surface quenching, finishing, quality inspection, packaging and storage. Before packaging the supporting shafts, the supporting shafts need to be cleaned and oiled. Oiling can form a protective film on the surface of the supporting shafts to prevent oxygen, moisture and acidic substances in the air from corroding the metal surface, thereby preventing the supporting shafts from rusting. Oiling can provide a certain lubrication effect and reduce the wear of the supporting shafts during storage and transportation. High-quality anti-rust oil can reduce the vibration value and vibration fluctuation value of the supporting shafts, thereby improving the working efficiency and service life of the supporting shafts. Oiling can prevent the supporting shafts from being contaminated by dust, water-soluble inorganic salts, marking inks, oxide layers or chemical precipitates produced by other chemical changes during storage and transportation.

[0004] Since the support shaft has a tube through hole in the middle and the outer contour is inconsistent, it is difficult to fully oil the support shaft, and at present, manual oiling is mostly used, which is inefficient. Summary of the invention

[0005] The invention provides a mining support shaft production device, aiming to solve the problem in the related art that it is difficult to efficiently oil the support shaft.

[0006] A mining support shaft production equipment comprises a conveyor 1, a base frame and a conveyor 2 which are arranged in sequence, wherein a bearing member is rotatably provided on the base frame and a shaft sleeve is fixedly provided, a base for driving the support shaft to rotate is provided on the bearing member, a plurality of clamping blocks are provided on the base member along its circumference, a sliding rod cooperating with the clamping block is provided in the bearing member through sliding of an elastic member 1, a guide member cooperating with the sliding rod is provided on the shaft sleeve, two carrier plates are rotatably provided on the bearing member, a plurality of smearing members for oiling the outer peripheral surface of the support shaft are provided on the carrier plates along their length extension direction, and the smearing members are connected to the bearing member through the elastic member 1. The second elastic member is slidably connected with the carrier plate, and the shaft sleeve is provided with a bevel rack one and a bevel rack two that cooperate with the carrier plate; during the process of the bearing member rotating from the side facing the first conveyor to the vertical state, the two carrier plates can approach each other so that the smearing member contacts the outer peripheral surface of the supporting shaft, and the clamping block can clamp the supporting shaft. During the process of the bearing member rotating from the vertical state to the side facing the second conveyor, the base can rotate, and then the clamping block disengages from the clamping of the supporting shaft, and the two carrier plates move away from each other, so that the supporting shaft falls on the second conveyor and is transported away by the second conveyor.

[0007] Preferably, the smearing member includes a shaft cylinder slidably connected to the carrier plate, a ball is installed at one end of the shaft cylinder close to the supporting shaft, a sponge is provided at one end of the shaft cylinder close to the supporting shaft, the ball protrudes outward from the sponge, and a tube for supplying oil to the sponge is provided at one end of the shaft cylinder away from the supporting shaft.

[0008] Preferably, a retaining ring is provided at one end of the shaft cylinder away from the supporting shaft, and the second elastic member is provided on the outer periphery of the shaft cylinder and located between the retaining ring and the carrier plate.

[0009] Preferably, the bearing member is provided with a vertical axis for mounting a carrier plate, a limiting rod is provided on the carrier plate through three sliding movements of an elastic member, and two limiting holes cooperating with the limiting rod are provided on the bearing member along the circumference of the vertical axis, with an angle of 90° between the two limiting holes.

[0010] Preferably, a bevel gear 1 is fixedly provided on one end of the carrier plate close to the bearing member, and the bevel gear 1 cooperates with the bevel rack 1 and the bevel rack 2 through a transmission member.

[0011] Preferably, one end of the slide bar close to the clamping block has a conical surface 1 and a retaining surface 1, and the clamping block has a conical surface 2 and a retaining surface 2 that match the slide bar.

[0012] Preferably, the clamping block is connected to the base through elastic member 4 and can slide radially along the base. The outer periphery of the guide member has guide surface 1, guide surface 2, guide surface 3 and guide surface 4 arranged in sequence, and guide surface 3 corresponds to the spacing area between bevel rack 1 and bevel rack 2.

[0013] Preferably, a bearing rod is coaxially disposed at one end of the base away from the bearing member, and a plurality of top rods are spaced apart at the periphery of one end of the bearing rod away from the base. The top rods are telescopic rods and can be telescoped along the radial direction of the bearing rod.

[0014] Preferably, the support member has inclined portions respectively cooperating with the first conveyor and the second conveyor.

[0015] Preferably, the base frame is provided with a support shaft rotatably matched with the bearing member and the shaft sleeve, a motor 1 for driving the bearing member to rotate is installed on the base frame, and a motor 2 for driving the base to rotate is installed in the bearing member.

[0016] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: during the working process, multiple supporting shafts are placed on conveyor one at intervals and the large ends of the supporting shafts are facing conveyor two. During this process, the supporting shafts gradually approach the load-bearing member and are passed through the load-bearing rod. Then, the motor one is controlled to rotate so that the load-bearing member rotates clockwise around the support shaft until the load-bearing rod is in a vertical state. During this process, the supporting shaft can remain coaxial with the load-bearing rod under the action of its own weight, and the bevel gear three is meshed with the bevel rack one so that the two carriers can approach each other. Under the action of the elastic member two, the ball contacts the outer peripheral surface of the supporting shaft, the sponge is squeezed into contact with the outer peripheral surface of the supporting shaft and fits with the outer contour of the supporting shaft, the conical surface one stops against the conical surface two, and then the retaining surface one stops against the retaining surface two, so that the clamping block clamps the supporting shaft, and at this time the limit rod is stuck in another limit hole.

[0017] During the process of the load-bearing rod rotating from a vertical state to the side facing conveyor two, motor two is controlled to rotate in the interval area between bevel rack one and bevel rack two, so that the sponge can fully oil the outside of the support shaft. Then, when bevel gear three and bevel rack two begin to mesh, the two carrier plates can gradually move away from each other, and the limiting rod disengages from the other limiting hole mentioned above. When the load-bearing rod is parallel to the upper end face of conveyor two, the large end of the support shaft contacts the conveyor belt surface of conveyor two, and then conveyor two can transport the support shaft away, thereby realizing efficient oiling operation of the support shaft.
