Background Art

[0002] During the construction of the elevator shaft wall, there will be some deviations in the size. When installing the car in the elevator shaft wall, the error between the car and the elevator shaft wall must be adjusted through the elevator guide rail bracket. Since the elevator guide rail bracket is welded to the elevator shaft wall, when adjusting the spacing between the elevator guide rail brackets, it is necessary to first knock off the welding point between the elevator guide rail bracket and the elevator shaft wall, and then adjust the spacing of the elevator guide rail bracket. After the adjustment is completed, the elevator guide rail bracket is re-welded and fixed. The adjustment operation is relatively cumbersome, and the operation in a high-altitude environment is more inconvenient, and it takes a lot of time and effort. However, the elevator guide rail bracket spacing adjustment in the prior art has the following defects:

[0003] 1. In the prior art, the elevator guide rail bracket spacing adjustment device cannot accurately and effectively adjust the spacing of the elevator guide rail bracket, thereby increasing people's work pressure, failing to meet people's work needs, and reducing the working efficiency of the adjustment device;

[0004] 2.

Through the arrangement of a movable frame, a first hollow elastic member, and a second rubber member, the two movable frames approach each other to drive the two first hollow elastic members and the second rubber member to approach each other. The two second rubber members approach each other and contact the opposite ends of the T-shaped guide rail bracket respectively, thereby performing a preliminary clamping and fixing effect on the T-shaped guide rail bracket. Then, through the arrangement of the second hollow elastic member, the telescopic tube, the first guide block, and the second guide block, the two movable frames continue to approach each other, and the two second rubber members are pressed against the opposite ends of the T-shaped guide rail bracket, thereby squeezing the two first hollow elastic members. The elastic force generated by the squeezing of the two first hollow elastic members acts on the two second rubber members respectively, so as to strengthen the clamping force of the two second rubber members on the opposite ends of the T-shaped guide rail bracket; and the two first hollow elastic members are squeezed, so that the solution in the two first hollow elastic members enters the two second hollow elastic members through the two telescopic tubes respectively. The two second hollow elastic members expand and push the two pairs of first guide blocks to move closer to each other; one end of the first guide block is in sliding contact with the inclined surface of one end of the second guide block, so that each pair of second guide blocks are brought closer to each other; each pair of second guide blocks is brought closer to each other, driving the two first clamping plates and the two first rubber members to move closer to each other, so that the two pairs of first rubber members can squeeze and fix the two sides of the opposite ends of the T-shaped guide rail bracket, thereby improving the stability of clamping the opposite ends of the T-shaped guide rail bracket and avoiding shaking or displacement during the process of adjusting the spacing between the two T-shaped guide rail brackets.

[0020] The present invention provides a fast-adjustable elevator guide rail bracket spacing adjustment device. Through the arrangement of the second movable plate and the clamping block, the two first movable plates approach each other, driving the two second movable plates and the two clamping blocks to approach each other. The two clamping blocks approach each other to initially clamp and fix the two sides of one end of the T-shaped guide rail bracket. Then, through the arrangement of the elastic block, the slider, and the third movable plate, the two clamping blocks are supported by the two sides of one end of the T-shaped guide rail bracket to cooperate with the two second movable plates to continue to approach each other. Through the two sides of one end of the second movable plate, the two sides of the second movable plate are respectively in sliding contact with the inclined surfaces of one end of the two third movable plates, so that the two third movable plates are moved away from each other; the two third movable plates move away from each other, respectively driving the two sliders and the elastic blocks to move away from each other.

A stepper motor 46 is installed on one side of each shell 10. A double-threaded screw rod 47 is provided at the output end of the stepper motor 46.

A first elastic member 49 is connected between the sides of the two first frames 11 that are close to each other, and two second elastic members 50 are respectively connected between the sides of the shell 10 that are away from each other.

[0051] In the initial state, the first airbag 37 is in a deflated state, and the second airbag 52 is in an expanded state.

[0052] Specific use of the present invention:

[0053] The staff installs and fixes the two adjustment components on the two side walls of the elevator shaft 51, and then symmetrically places two T-shaped guide rail brackets 45 on the adjustment components. At this time, the two T-shaped guide rail brackets 45 are respectively located in the two first frames 11 on the adjustment components. Among them, the T-shaped guide rail bracket 45 is a T-shaped structure, and the opposite ends of the T-shaped guide rail bracket 45 are located in the first frame 11, and one end of the T-shaped guide rail bracket 45 is used to guide and limit the up and down movement of the car.

[0054] When adjusting the distance between the two T-shaped guide rail brackets 45, the control system controls the small air pump 35 to start, and the small air pump 35 starts to suck the gas in the second air bag 52 into the first air bag 37, so that the first air bag 37 expands and pushes the second push rod 41 and the pressure plate 42 to move upward. The pressure plate 42 moves upward to vertically squeeze the third hollow elastic member 36, so that the third hollow elastic member 36 deforms horizontally and pushes the two push rods 13 to move. One end of the two push rods 13 is in sliding contact with the inclined surface of one end of the two first push rods 14, so that the two first push rods 14 and the two slide plates 15 are close to each other. The two slides 15 approach each other, driving the two pairs of second connecting rods 17 and the two first movable plates 16 to approach each other. The two first movable plates 16 approach each other, driving the two first connecting rods 19 and the movable frame 20 to approach each other. The two movable frames 20 approach each other, driving the two first hollow elastic members 23 and the second rubber members 24 to approach each other. The two second rubber members 24 approach each other and contact the opposite ends of the T-shaped guide rail bracket 45, thereby performing a preliminary clamping and fixing effect on the T-shaped guide rail bracket 45. The two slides 15 approach each other to compress the two first springs 18 to generate elastic force, which is conducive to moving and resetting the two slides 15 under the action of the elastic force of the two first springs 18. The second airbag 52 contracts to reduce the degree of squeezing of the plurality of limit blocks 38, which is conducive to the horizontal sliding of the two first frames 11 in the housing 10.

[0055] Next, the two movable frames 20 continue to approach each other, and the two second rubber members 24 are pressed against the opposite ends of the T-shaped guide rail bracket 45, thereby squeezing the two first hollow elastic members 23. The elastic forces generated by the squeezing of the two first hollow elastic members 23 act on the two second rubber members 24 respectively, so as to strengthen the clamping force of the two second rubber members 24 on the opposite ends of the T-shaped guide rail bracket 45; and the two first hollow elastic members 23 are squeezed, so that the solutions in the two first hollow elastic members 23 enter the two second hollow elastic members 25 respectively through the two telescopic tubes 26, and the two second hollow elastic members 25 expand and push the two pairs of first guide blocks 27 to move closer to each other; through the sliding contact between one end of the first guide block 27 and the inclined surface of one end of the second guide block 28, each pair of second guide blocks 28 is brought closer to each other. Each pair of second guide blocks 28 approaches each other, driving the two first clamping plates 21 and the two first rubber members 22 to approach each other, so that the two pairs of first rubber members 22 can squeeze and fix the two sides of the opposite ends of the T-shaped guide rail bracket 45, thereby improving the stability of clamping the opposite ends of the T-shaped guide rail bracket 45 and avoiding shaking or displacement during the process of adjusting the spacing between the two T-shaped guide rail brackets 45.

[0056] At the same time, the two first movable plates 16 approach each other, driving the two second movable plates 29 and the two clamping blocks 30 to approach each other, and the two clamping blocks 30 approach each other to initially clamp and fix the two sides of one end of the T-shaped guide rail bracket 45. Then, the two clamping blocks 30 are supported by the two sides of one end of the T-shaped guide rail bracket 45 to cooperate with the two second movable plates 29 to continue to approach each other, and the two sides of one end of the second movable plates 29 are respectively in sliding contact with the inclined surfaces of one end of the two third movable plates 33, so that the two third movable plates 33 are separated from each other; the two third movable plates 33 are separated from each other and respectively drive the two sliders 32 and the elastic blocks 31 to move away from each other, and the two elastic blocks 31 are separated from each other and respectively contact one side of the first frame 11 and one side of the opposite ends of the T-shaped guide rail bracket 45, which is conducive to the limiting and fixing of the clamping blocks 30 and improves the stability of the two clamping blocks 30 clamping one end of the T-shaped guide rail bracket 45. The two third movable plates 33 move away from each other to compress the two pairs of second springs 34 to generate elastic force, so that the two third movable plates 33 are reset close to each other under the elastic force of the two pairs of second springs 34. At the same time, the expansion of the third hollow elastic member 36 in the horizontal direction pushes the second clamping plate 43 and the third rubber plate 44 to move, and the movement of the third rubber plate 44 squeezes and fixes the T-shaped guide rail bracket 45.

[0057] Finally, the stepper motor 46 starts to drive the double-threaded screw 47 to rotate. The two ends of the double-threaded screw 47 have opposite thread directions, and the two ends of the double-threaded screw 47 are respectively in threaded contact with the two movable blocks 48. The rotation of the double-threaded screw 47 can drive the two movable blocks 48 to move closer to or away from each other. The two movable blocks 48 move to drive the two first frames 11 and the two T-guide rail brackets 45 to move to adjust the distance between the two T-guide rail brackets 45. The two first frames 11 move, and a plurality of elastic protrusions 39 are squeezed and contacted with the card slot 40, so as to buffer and limit the two first frames 11, so as to smoothly and quickly adjust the spacing between the two T-guide rail brackets 45. Then, the two ends of one side of the limit block 38 are in inclined contact, and a plurality of elastic protrusions 39 are spaced and distributed on the inclined surfaces and planes at both ends of the limit block 38, so as to gradually buffer the movement of the first frame 11, which is conducive to quickly adjusting the spacing between the two T-guide rail brackets 45 and timely positioning and fixing.

[0058] When the spacing between the two T-rail brackets 45 is adjusted, the control system controls the small air pump 35 to start, and the small air pump 35 starts to suck the gas in the first airbag 37 into the second airbag 52. The second airbag 52 expands to push the movement of the plurality of limit blocks 38 and the movement of the plurality of elastic protrusions 39, so that the plurality of elastic protrusions 39 on the plane of the limit block 38 enter the corresponding card slot 40, so as to limit and fix the first frame 11, and avoid the displacement of the two first frames 11 in the shell 10. At this time, the first airbag 37 contracts to reduce the clamping force of the clamping assembly on the T-rail bracket 45, but does not affect the stability of the clamping assembly on the T-rail bracket 45. Among them, the two second elastic members 50 and the first elastic member 49 are used to reduce dust from entering the shell 10, and avoid the two first frames 11 from being stuck when moving in the shell 10.

[0059] The present invention is a fast-adjustable elevator guide rail bracket spacing adjustment device. By setting a movable frame 20, a first hollow elastic member 23, and a second rubber member 24, two movable frames 20 approach each other to drive the two first hollow elastic members 23 and the second rubber members 24 to approach each other. The two second rubber members 24 approach each other and contact the opposite ends of the T-shaped guide rail bracket 45, thereby preliminarily clamping and fixing the T-shaped guide rail bracket 45. Then, by setting the second hollow elastic member 25, the telescopic tube 26, the first guide block 27, and the second guide block 28, the two movable frames 20 continue to approach each other, and the two second rubber members 24 are pressed against the opposite ends of the T-shaped guide rail bracket 45, thereby squeezing the two first hollow elastic members 23. The elastic force generated by the squeezing of the two first hollow elastic members 23 acts on the two second rubber members 24 respectively, so as to strengthen the clamping force of the two second rubber members 24 on the opposite ends of the T-shaped guide rail bracket 45; and the two first hollow elastic members 23 are squeezed, so that the solution in the two first hollow elastic members 23 enters the two second hollow elastic members 23 through the two telescopic tubes 26 respectively. Inside the elastic member 25, the two second hollow elastic members 25 expand and push the two pairs of first guide blocks 27 to move closer to each other; one end of the first guide block 27 is in sliding contact with the inclined surface of one end of the second guide block 28, so that each pair of second guide blocks 28 are brought closer to each other; each pair of second guide blocks 28 approaching each other drives the two first clamping plates 21 and the two first rubber members 22 to approach each other, so that the two pairs of first rubber members 22 can squeeze and fix the two sides of the opposite ends of the T-shaped guide rail bracket 45, improve the stability of clamping the opposite ends of the T-shaped guide rail bracket 45, and avoid shaking or displacement during the process of adjusting the spacing between the two T-shaped guide rail brackets 45.

[0060] The present invention is a device for adjusting the spacing of elevator guide rail brackets that is easy to adjust quickly. By setting the second movable plate 29 and the clamping block 30, the two first movable plates 16 are brought close to each other to drive the two second movable plates 29 and the two clamping blocks 30 to be close to each other. The two clamping blocks 30 are brought close to each other to perform a preliminary clamping and fixing effect on both sides of one end of the T-shaped guide rail bracket 45. Through the arrangement of the elastic block 31, the slider 32, and the third movable plate 33, the two clamping blocks 30 are pressed against the two second movable plates 29 on both sides of one end of the T-shaped guide rail bracket 45 to continue to approach each other, and the two sides of one end of the second movable plate 29 are respectively in sliding contact with the inclined surfaces of one end of the two third movable plates 33, so that the two third movable plates 33 move away from each other; the two third movable plates 33 move away from each other and respectively drive the two sliders 32 and the elastic blocks 31 to move away from each other, and the two elastic blocks 31 move away from each other and respectively contact one side of the first frame 11 and one side of the opposite end of the T-shaped guide rail bracket 45, which is beneficial to the limiting and fixing effect of the clamping blocks 30, and improves the stability of the two clamping blocks 30 clamping both sides of one end of the T-shaped guide rail bracket 45.

[0061] The present invention is a fast-adjustable elevator guide rail bracket spacing adjustment device. By setting a limit block 38, an elastic protrusion 39, and a slot 40, the two first frames 11 move, and a plurality of elastic protrusions 39 are pressed and contacted with the slot 40, so as to buffer and limit the two first frames 11, so as to smoothly and quickly adjust the spacing between the two T-shaped guide rail brackets 45. Then, both ends of one side of the limit block 38 are in inclined contact, and a plurality of elastic protrusions 39 are spaced and distributed on the inclined surfaces and planes at both ends of the limit block 38, so as to gradually buffer the movement of the first frame 11, which is conducive to quickly adjusting the spacing between the two T-shaped guide rail brackets 45 and timely positioning and fixing. Finally, by setting the second airbag 52, the expansion of the second airbag 52 pushes the movement of the plurality of limit blocks 38 and the plurality of elastic protrusions 39, so that the plurality of elastic protrusions 39 on the plane of the limit block 38 enter the corresponding card groove 40, so as to limit and fix the first frame body 11, and avoid displacement of the two first frames 11 in the shell 10.
