DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, embodiment 1 provides a tool for manually disassembling a reducer worm gear of a railway coal hopper car, comprising a support 1, a horizontal action component 2 arranged on the support 1, a sleeve groove 3 for sleeve-mounting the worm gear at one end of the horizontal action component 2, and a jack 4 arranged at the bottom end of the support 1.

[0023] When in use, the sleeve groove 3 is put on the worm so that the horizontal acting component 2 is located below the worm handwheel, and the jack 4 is operated to make the support 1 push the horizontal acting component 2, and the horizontal acting component 2 pushes the worm and pulls out the worm.

[0024] An oblique support 5 is provided between the other end of the horizontal acting component 2 and the pillar 1, and the top and bottom ends of the oblique support 5 are rotatably connected to the horizontal acting component 2 and the pillar 1 respectively through a pin. The oblique support 5 is used to improve the balance of the horizontal acting component 2 when the worm is pushed up. The sleeve groove 3 is a "U"-shaped groove. In the application process, the notch is directly aligned with the worm and then the worm is sleeved.

[0025] like Figures 2 to 4 As shown, on the basis of the first embodiment, the second embodiment comprises a horizontal acting component 2 including a first plate body 2.1, a sleeve block 2.2 and a pressure rod 2.3. The first plate body 2.1 is connected to the pillar 1. Two sleeve blocks 2.2 are slidably arranged on the top of one end of the first plate body 2.1. The two sleeve blocks 2.2 are relatively distributed. An arc groove 2.4 is provided on the opposite side of the two sleeve blocks 2.2, and the two arc grooves 2.4 form a sleeve groove 3. The pressure rod 2.3 is slidably installed on the first plate body 2.1 in the height direction. The top end of the pressure rod 2.3 extends out of the first plate body 2.1, and the pressure rod 2.3 controls the two sleeve blocks 2.2 to clamp the worm by downward displacement.

[0026] By setting the sleeve groove 3 to be composed of two arc grooves 2.4, when the two sleeve plates clamp the worm, they are wrapped outside the worm. In this state, the horizontal action component 2 and the worm are effectively connected and can limit each other. The worm makes the horizontal action component 2 always perpendicular to the worm. In this way, the horizontal action component 2 is limited by the worm so that the support 1 and the jack 4 are parallel to the worm as a whole. Then, in the process of the subsequent jack 4 pushing up the support 1, the horizontal action component 2 and the worm, the lifting trajectory of the horizontal action component 2 is parallel to the worm, which can effectively protect the worm and prevent the worm from bending.

[0027] It should be noted that, by configuring the sleeve groove 3 to be composed of two arc grooves 2.4, the operator can determine the vertical state between the horizontal acting component 2 and the worm by observing whether the sleeve groove 3 is effectively fitted onto the worm, and then can directly determine the parallel state between the support 1 and the worm.

[0028] In the initial state, the top end of the pressure rod 2.3 extends out from the top of the horizontal acting component 2. Before the jack 4 pushes the support 1 and the support 1 drives the horizontal acting component 2 to pull out the worm, the top end of the pressure rod 2.3 is blocked by the worm handwheel and moves downward relative to the horizontal acting component 2. During this process, the second rod body 2.3.2 squeezes the two sleeve blocks 2.2 inward, and the two sleeve shells clamp the worm from both sides.

[0029] The pressure rod 2.3 includes a first rod body 2.3.1 in a vertical state and a second rod body 2.3.2 in a "human" shape arranged at the bottom of the first rod body 2.3.1, and two sleeves 2.2 are connected to the second rod body 2.3.2. When the top of the first rod body 2.3.1 contacts the worm handwheel to make the pressure rod 2.3 move downward, the two sides of the second rod body 2.3.2 push the two sleeves 2.2 to move relative to each other, so that the two arc grooves 2.4 are respectively sleeved on the worm from both sides. The surface of the sleeve 2.2 is rotatably installed with a sliding sleeve 6, and the sliding sleeve 6 is slidably sleeved on the second rod body 2.3.2. When the second rod body 2.3.2 moves downward, the sliding sleeve 6 moves upward on the second rod body 2.3.2, and at the same time, the sliding sleeve 6 drives the sleeve 2.2 to move inward. On the contrary, when the second rod body 2.3.2 moves upward, the sleeve 2.2 loosens the worm.

[0030] The two bottom ends of the second rod 2.3.2 are connected by a support plate 7, and a pull-up spring 8 is provided between the top of the support plate 7 and the bottom of the first plate 2.1. In the initial state, the pull-up spring 8 uses its elastic force to keep the top of the first rod 2.3.1 extending from the top of the first plate 2.1.

[0031] Two horizontal action components 2 are provided on the pillar 1, and the two second rod bodies 2.3.2 are fixedly connected. Specifically, the top of the first rod body 2.3.1 in the pressure rod 2.3 located at the bottom is fixedly connected to the bottom middle part of the support plate 7 located at the top. By providing two horizontal action components 2, double-point calibration is achieved in the length direction of the pillar 1, and then before the worm is pulled out, the two pressure rods 2.3 are synchronously displaced downward so that the upper and lower sets of blocks 2.2 clamp the worm at the same time. At this time, it can better ensure that the pillar 1 is parallel to the worm and the horizontal action component 2 is perpendicular to the worm, so that the worm will not bend when it is pulled out.

[0032] The pillar 1 includes an upper column 1.1, a lower column 1.2, and a support spring 1.3 arranged between the bottom end of the upper column 1.1 and the top end of the lower column 1.2, and the bottom end of the upper column 1.1 is inserted into the top end of the lower column 1.2, and the support spring 1.3 is located in the top end of the lower column 1.2. The pillar 1 is set to be elastically retractable. In the initial stage of the jack 4 pushing the pillar 1 up, after the top end of the pressure rod 2.3 contacts the worm hand wheel, as the jack 4 continues to push the column up, the support spring 1.3 is compressed. Using the elastic force of the support spring 1.3, the pressure rod 2.3 is pressed down by the worm hand wheel so that the two sets of sleeves 2.2 are both sleeved with worms. As the jack 4 continues to push up, the support spring 1.3 is compressed, and the clamping force of the sleeve 2.2 clamping the worm continues to increase. By utilizing the elastic expansion and contraction performance of the support spring 1.3, when it is observed that the sleeve block 2.2 is not effectively sleeved on the worm gear, the jack 4 can be manually lifted up to make it leave the ground to adjust the position, so that the sleeve block 2.2 is effectively sleeved on the worm gear, and the pillar 1 is parallel to the worm gear, thereby conveniently adjusting the state of the pillar 1.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
