DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0028] Please refer to Figs. 1-3 In the embodiments of the utility model, a construction hoist chassis comprises a chassis body 1, mounting holes 2 and connecting assemblies 3. The mounting holes 2 are arranged in four and are arranged in a rectangular distribution on the top of the chassis body 1 and completely penetrate the bottom of the chassis body 1. The chassis body 1 is connected and fixed with embedded bolts through the mounting holes 2. The connecting assemblies 3 are arranged in four and are arranged in a matrix distribution in the middle of the chassis body 1. The connecting assembly 3 comprises a connecting seat 301, a plug-in hole slot 302, a connecting screw hole 303 and a horizontal screw hole 304.
[0029] The connecting seat 301 is fixed to the outer wall side of the middle of the chassis body 1. The plug-in hole slot 302 and the connecting screw hole 303 are arranged on the top of the chassis body 1. The plug-in hole slot 302 is used for inserting the bottom end of a hoist standard section. The connecting screw hole 303 is used for threadedly connecting the connecting bolt of the hoist standard section.
[0030] The horizontal screw hole 304 penetrates from one end of the connecting seat 301 to the other end of the connecting seat 301, and the leveling assembly 4 is connected to the connecting seat 301 through the horizontal screw hole 304, and the leveling assembly 4 extends from one end of the connecting seat 301 to the bottom end of the connecting seat 301;
[0031] The leveling assembly 4 comprises a supporting unit and a reinforcing unit;
[0032] The supporting unit is used to realize height adjustment and filling between the bottom of the connecting seat 301 and the ground, so as to realize horizontal adjustment of the chassis main body 1;
[0033] The reinforcing unit is used to form a reinforcing operation between the two groups of supporting units distributed on the same side of the chassis main body 1;
[0034] The supporting unit comprises an L-shaped base 401, a vertical straight slot 402, and an adjusting bolt 403;
[0035] The horizontal part of the L-shaped base 401 is distributed at the bottom end of the connecting seat 301, and the vertical part of the L-shaped base 401 is distributed at one end of the connecting seat 301, and the bottom of the connecting seat 301 and the top of the horizontal part of the L-shaped base 401 are both inclined surface structures, and the height adjustment between the bottom of the connecting seat 301 and the ground is realized by the horizontal movement of the L-shaped base 401 relative to the connecting seat 301;
[0036] The vertical straight slot 402 is opened at one end of the vertical part of the L-shaped base 401 and penetrates completely to the other end of the vertical part, the adjusting bolt 403 penetrates the vertical straight slot 402 and is threadedly connected with the horizontal screw hole 304, and the L-shaped base 401 is pushed towards the connecting seat 301 by rotating the adjusting bolt 403;
[0037] The reinforcing unit comprises a bidirectional screw rod 404 and a reinforcing nut 405;
[0038] The bidirectional screw rod 404 penetrates the vertical straight slots 402 on the two L-shaped bases 401 distributed on the same side of the chassis main body 1;
[0039] The two reinforcing nuts 405 are respectively threadedly connected to the two ends of the bidirectional screw rod 404 and respectively abut the end faces of the vertical parts of the two L-shaped bases 401, so as to realize spacing limiting of the two L-shaped bases 401.
[0040] In this embodiment, the chassis main body 1 is sleeved outside the embedded bolt through the mounting hole 2, the lower surface of the L-shaped base 401 in the initial state is flush with the lower surface of the chassis main body 1, and the upper surface of the horizontal part of the L-shaped base 401 abuts the lower surface of the connecting seat 301;
[0041] When the chassis body 1 needs to be leveled, only the adjusting bolt 403 at the position that needs to be raised needs to be tightened, which will push the L-shaped pad 401 to move in the direction of the connecting seat 301. Due to the structure of the transverse part of the L-shaped connecting seat 401 and the inclined surface of the connecting seat 301, the L-shaped connecting seat 401 will be pressed to move upwards on the connecting seat 301. Thus, the part of the chassis body 1 corresponding to the connecting seat 301 will move upwards, thereby achieving the effect of adjusting the level of the chassis body 1.
[0042] After completing the level adjustment of the chassis body 1, the positions of the two L-shaped connecting seats 401 on the same side of the chassis body 1 can be reinforced. At this time, the two reinforcing nuts 405 on the bidirectional screw rod 404 can be rotated to make the two reinforcing nuts 405 tightly fit the end faces of the two L-shaped connecting seats 401, respectively. Thus, the distance between the two L-shaped connecting seats 401 can be fixed, thereby ensuring the stability of the positions of the L-shaped connecting seats 401 and maintaining the stability of the level of the chassis body 1.
[0043] Through the cooperation of the above-mentioned multiple parts, the level of the chassis body 1 can be conveniently adjusted. Compared with the traditional way of adding gaskets one by one for raising and leveling, the adjusting precision is higher through the way of pressing the transverse part of the L-shaped connecting seat 401 and the inclined surface of the connecting seat 301. Moreover, the operation is more convenient and efficient through the way of rotating the adjusting bolt 403 to complete the adjustment.
[0044] Please refer to Figs. 1-3 , the outer walls of the two ends of the bidirectional screw rod 404 are formed with two sections of helical grooves with opposite directions. The inner threads of the two reinforcing nuts 405 are matched with the opposite helical grooves, respectively.
[0045] The outer wall threads of the two adjusting bolts 403 in the two groups of supporting units are opposite in direction to the helical grooves at the corresponding positions.
[0046] The two ends of the bidirectional screw rod 404 do not contact the connecting seat 301.
[0047] In this embodiment, the adjusting bolt 403 and the reinforcing nut 405 corresponding to one L-shaped pad 401 have different moving directions when they are rotated in the same direction, so that the cooperation of the two has an anti-loosening effect.
[0048] In addition, through the structure that the two ends of the bidirectional screw rod 404 do not contact the connecting seat 301, the two L-shaped pads 401 will transmit the pressing force from the connecting seat 301 to each other, thereby achieving the effect of fixing the positions of the L-shaped pads 401.
[0049] Please refer to Figs. 1-3 , the horizontal screw hole 304, the plug-in hole groove 302, and the connecting screw hole 303 are not in communication with each other, and the top of the connecting seat 301 protrudes above the upper surface of the chassis body 1.
[0050] In the embodiment, the top of the connecting seat 301 protrudes from the upper surface of the chassis main body 1, so that the plug hole slot 302 and the connecting screw hole 303 have sufficient depth, thereby ensuring the stable connection of the standard section with the connecting seat 301.
[0051] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
