[0036] With reference to Figures 1 to 4 The utility model discloses a high guiding precision's reduction gearbox, including base 100, box 200, telescopic oil cylinder 300 and inclined strut assembly 400, base 100 is installed with guide column 110, and box 200 is installed in guide column 110 and is lifted, telescopic oil cylinder 300, fixed end is installed in box 200, and movable end is connected with base 100;Telescopic oil cylinder 300 is used to drive box 200 along guide column 110 vertical lifting, and box 200 is used to be connected with drill rod to drive drill rod operation;Inclined strut assembly 400 includes first connecting piece 410, second connecting piece 420 and inclined strut 430, and first connecting piece 410 is sleeved in guide column 110, and can slide along guide column 110;Second connecting piece 420 is installed in box 200, and the first end of the length direction of inclined strut 430 is hinged with first connecting piece 410, and the second end of the length direction of inclined strut 430 is slidably installed in second connecting piece 420.The high guiding precision's reduction gearbox of utility model embodiment, through setting up inclined strut assembly 400 between box 200 and guide column 110, inclined strut assembly 400 includes inclined strut 430, and inclined strut 430 can better disperse the stress of box 200 to the axial direction of guide column 110, thereby improving the stress condition of guide column 110, reducing the risk of the problems such as the incommode sliding of box 200, the scraping column, prolonging the service life of equipment.

[0037] The reduction gearbox in the embodiment of the utility model is two-column two-cylinder type, and the guide column 110 is provided with two, and the two guide columns 110 are arranged at intervals along the width direction of the box 200, and the two guide columns 110 are both arranged in the box 200;The telescopic oil cylinder 300 is provided with two, and the two telescopic oil cylinders 300 are respectively installed on the two sides of the width direction of the box 200;In order to improve the stability of the lifting of the box 200, the top of the two guide columns 110 is connected through the reinforcing plate 120. Figure 1 、 Figure 2 、 Figure 4As shown, the reinforcing plate 120 is a long strip-shaped plate, both ends of the length direction of the reinforcing plate 120 are provided with through holes for the guide column 110 to pass through, and the two guide columns 110 are respectively arranged in the two through holes. By connecting the two guide columns 110 through the reinforcing plate 120, the two guide columns 110 can be connected as a whole, thereby improving the torsional and bending resistance of the guide column 110, and further improving the service life of the guide column 110, and reducing the probability of problems such as poor sliding and scratching of the guide column 110 on the box body 200.

[0038] In the embodiment of the utility model, two diagonal bracing assemblies 400 are also arranged, and the two diagonal bracing assemblies 400 are respectively arranged on the width direction of the box body 200, and the two diagonal bracing assemblies 400 are respectively used for connecting the two guide columns 110 and the box body 200. By arranging the two diagonal bracing assemblies 400 to be respectively connected with the two guide columns 110, the stress of the two guide columns 110 can be evenly distributed, and the weight of the box body 200 can be better and more evenly shared, thereby avoiding problems such as eccentric wear of the single guide column 110.

[0039] In the embodiment of the utility model, referring to Figure 1 、 Figure 2 As shown, the first connecting piece 410 is sleeved on the guide column 110, the first connecting piece 410 is provided with a radially protruding connecting structure, the first end of the diagonal bracing rod 430 is hinged with the connecting structure, and the first connecting piece 410 is arranged below the box body 200. Specifically, when the box body 200 is in a low position, the bottom of the guide column 110 is connected with the base 100, so the moment is short, and the operation of the box body 200 will not cause a large impact on the guide column 110. When the box body 200 is in a higher position, the moment becomes longer, the operation of the box body 200 will cause a large bending moment of the guide column 110, thereby causing the guide column 110 to be bent and deformed, so that the box body 200 will be scratched with the guide column 110 when vertically lifting. At this time, if the first connecting piece 410 is arranged above the box body 200, when the guide column 110 is bent and deformed, the center of gravity of the box body 200 will still be on the outside of the guide column 110 and at a higher position of the guide column 110, so that the diagonal bracing assembly 400 cannot effectively disperse the moment of the guide column 110. By arranging the first connecting piece 410 below the box body 200, the weight of the box body 200 will be transmitted to the axial direction of the guide column 110 along the diagonal bracing rod 430, and then extended downward, thereby improving the stress condition of the guide column 110.

[0040] In addition, referring to Figure 2As shown, a triangle is formed between the diagonal bracing rod 430, the guide column 110 and the box body 200, the triangle has stability, and therefore the diagonal bracing assembly 400 can effectively improve the stability of the connection between the box body 200 and the guide column 110.

[0041] In the embodiment of the utility model, the fixed end of telescopic oil cylinder 300 is connected with box body 200 through round nut 310, and the height of first connecting piece 410 in vertical direction is not greater than the height of round nut 310 in vertical direction. Figure 2 For example, if the movable end of telescopic oil cylinder 300 is completely retracted, the box body 200 will be at the lowest point position, at this time, the round nut 310 is basically in the position of contacting with the base 100, in order to avoid the influence of first connecting piece 410 on the telescopic movement of telescopic oil cylinder 300, so that the box body 200 can still move to the lowest point position, therefore, the height of first connecting piece 410 in vertical direction is not greater than the height of round nut 310 in vertical direction.

[0042] In the embodiment of the utility model, the second connecting piece 420 is provided with a sliding groove 421, and the second end of the diagonal bracing rod 430 in the length direction is slidably installed in the sliding groove 421. Figure 2 、 Figure 3 As shown, the length direction of the sliding groove 421 is the vertical direction, when the movable end of telescopic oil cylinder 300 is gradually retracted, the box body 200 will descend, and then drive the first connecting piece 410 to slide downward along the guide column 110, and the first connecting piece 410 will first slide downward to the position of contacting with the base 100. When the first connecting piece 410 slides to contact with the base 100, and the box body 200 continues to descend, the second end of the diagonal bracing rod 430 in the length direction will slide upward along the sliding groove 421, and then the first connecting piece 410 will rise relative to the guide column 110, until the box body 200 descends to the position of the round nut 310 contacting with the base 100.

[0043] In the embodiment of the utility model, when the second end of the diagonal bracing rod 430 in the length direction contacts with the bottom end of the sliding groove 421, at this time, the spacing between the first connecting piece 410 and the box body 200 is the largest, in order to facilitate understanding, in the embodiment, it is defined as the maximum set spacing; it can be conceived that the maximum set spacing should be not greater than the length of the sliding groove 421 in the vertical direction, so as to ensure that when the box body 200 slides to the lowest point position, the first connecting piece 410 has enough distance to rise, and will not cause damage to the diagonal bracing assembly 400.

[0044] In the embodiment of the utility model, the diagonal bracing assembly 400 further comprises an elastic member 440; the box body 200 is provided with an abutting block 210 protruding from the surface thereof, the second end of the diagonal bracing rod 430 in the length direction is provided with an abutting piece 431, and the two ends of the elastic member 440 are connected with the abutting block 210 and the abutting piece 431 respectively.Figure 3 As shown, the abutting block 210 is arranged above the second connecting piece 420, and the length extension direction of the elastic piece 440 is parallel to the length extension direction of the second connecting piece 420, specifically, parallel to the length extension direction of the sliding groove 421. The elastic piece 440 is always in a compressed state, and under the condition that the diagonal bracing assembly 400 is not subjected to external force, the elastic piece 440 will push the second end of the diagonal bracing rod 430 in the length direction, so that the second end of the diagonal bracing rod 430 in the length direction is in contact with the bottom of the sliding groove 421, thereby ensuring that the diagonal bracing rod 430 can always form a stable triangle with the box body 200 and the guide column 110, and further ensuring that the diagonal bracing assembly 400 can always play a role in improving the stress adjustment of the guide column 110. The elastic piece 440 is preferably a spring, and the outer periphery of the spring is preferably covered with a protective layer, thereby prolonging the service life of the elastic piece 440 in harsh environments such as mines.
