In the direction of straightening, the force rod 13 is inserted into the corresponding socket sleeve 12, and the elevator guide rail falls into the sleeve 16, and then the top of the force rod 13 is pulled, and the sleeve 16 is driven by the action of the lever to pull and adjust the elevator guide rail. In this process, the elevator guide rail is continuously subjected to force and is difficult to rebound. After the guide rail is straightened, the guide rail is fixed to the side wall of the elevator shaft, and then the force rod 13 is released, and the support plate 1 is moved downward to straighten the next guide rail. Through the above structure, the damage caused by the straightening of the hollow elevator guide rail can be reduced, and the rebound generated during the straightening of the guide rail can be reduced, thereby improving the accuracy of the straightened guide rail.

[0025] Reference Figures 1 to 4 As shown, the bottom of the support plate 1 is rotatably connected with a double-headed screw 2; both ends of the bottom of the support plate 1 are slidably connected with sliding columns 21; a pair of the sliding columns 21 are respectively threadedly connected to the two ends of the double-headed screw 2; the ends of the sliding columns 21 are fixedly connected with an extrusion plate 22; the side walls of the extrusion plate 22 are fixedly connected with a limiting rod 23; the limiting rod 23 is slidably connected to the end of the support plate 1; during operation, after the support plate 1 is moved to the vicinity of the elevator guide rail where straightening is required, the double-headed screw 2 is rotated to drive a pair of sliding columns 21 to move in opposite directions, and then drive a pair of extrusion plates 22 to be squeezed toward both sides of the elevator shaft, thereby fixing the support plate 1 inside the elevator shaft, making it difficult for the support plate 1 to slide or shake. At this time, the elevator guide rail can be conveniently straightened, reducing the influence of the shaking of the support plate 1 on the straightening of the elevator guide rail.

[0026] Reference Figures 1 to 5As shown, a gear 3 is fixedly connected to the middle of the double-headed screw 2; an adjusting handle 31 is rotatably connected to the middle of the gear 3; a slider 32 is slidably connected to the inside of the adjusting handle 31; a clamping plate 33 is fixedly connected to the side of the slider 32 facing the gear 3; a pair of springs 34 are fixedly connected to the side of the slider 32 away from the gear 3; the other end of the spring 34 is fixedly connected to the inner side wall of the adjusting handle 31; a slide cylinder 35 is slidably connected to the end of the adjusting handle 31 away from the gear 3; a pull rope 36 is fixedly connected to the inner side wall of the slide cylinder 35; the other end of the pull rope 36 is fixedly connected to the slider When working, when it is necessary to rotate the double-headed screw 2, the clamping plate 33 is clamped on the tooth part of the gear 3, and then the adjusting handle 31 is turned to drive the double-headed screw 2 to rotate. After rotating a certain angle, the slide cylinder 35 is pulled to drive the clamping plate 33 away from the gear 3 through the pull rope 36. At this time, the adjusting handle 31 is rotated back and the double-headed screw 2 will not rotate therewith. Through repeated operations, the double-headed screw 2 can be conveniently rotated to drive the pair of extrusion plates 22 to move. At the same time, the lever principle can be used to increase the extrusion force of the pair of extrusion plates 22 on the side wall of the elevator shaft, thereby improving the stability of the support plate 1.

[0027] Reference Figures 1 to 4 As shown, the side wall of the support plate 1 is slidably connected to a slide seat 4; the side wall of the slide seat 4 is rotatably connected to a pointer 41; the bottom end of the pointer 41 is fixedly connected to a counterweight block 42; during operation, after the support plate 1 is fixed, the slide seat 4 can be slid to a suitable position, and as the pointer 41 no longer shakes, the pointer 41 will remain perpendicular to the horizontal plane. At this time, the elevator guide rail can be easily observed to determine whether the elevator guide rail needs to be straightened and the direction of straightening.

[0028] Reference Figures 1 to 3 As shown, a top block 5 is fixedly connected to the inner bottom of the socket sleeve 12; an extension rod 51 is slidably connected to the inside of the force rod 13; the extension rod 51 is equal in length to the force rod 13; during operation, when the force rod 13 is inserted into the interior of the socket sleeve 12, the top block 5 will push the extension rod 51 upward, so that the top end of the extension rod 51 leaks out from the top end of the force rod 13, and at this time, the extension rod 51 can be partially pulled upward from the inside of the force rod 13, thereby increasing the lever arm, so that the steel guide rail can be straightened more labor-savingly.

[0030] Reference Figures 1 to 4 As shown, the side wall of the support plate 1 is fixedly connected with a plurality of hooks 7; the plurality of hooks 7 are evenly distributed on the side wall of the support plate 1; during operation, when straightening the elevator guide rails, other straightening tools carried can be hung on the hooks 7, so as to reduce the load on the operator and improve the convenience of work.

[0032] During operation, the support plate 1 is moved to the vicinity of the hollow elevator guide rail that needs to be straightened, so that one end of the support plate 1 is against the elevator shaft wall, and the force rod 13 is inserted into the corresponding socket 12 according to the direction in which the guide rail needs to be stretched and straightened, and the elevator guide rail falls into the inside of the clamping sleeve 16, and then the top of the force rod 13 is pulled, and the clamping sleeve 16 is driven to pull and adjust the elevator guide rail under the action of the lever. In this process, the elevator guide rail is continuously stressed and difficult to rebound. After the guide rail is straightened, the guide rail is fixed to the side wall of the elevator shaft, and then the force rod 13 is released, and the support plate 1 is moved downward Straighten the next guide rail. After moving the support plate 1 to the vicinity of the elevator guide rail that needs to be straightened, rotate the stud screw 2 to drive a pair of slide posts 21 to move in opposite directions, thereby driving a pair of extrusion plates 22 to squeeze toward both sides of the elevator shaft, thereby fixing the support plate 1 inside the elevator shaft, making it difficult for the support plate 1 to slide or shake. When it is necessary to rotate the stud screw 2, the clamping plate 33 is clamped on the tooth part of the gear 3, and then the adjusting handle 31 is rotated to drive the stud screw 2 to rotate. After rotating a certain angle, pull the slide cylinder 35 to drive the clamping plate 33 away from the gear 3 through the pull rope 36. At this time, the adjusting handle 31 is turned back and the double-headed screw 2 will not rotate with it. Through repeated operations, the double-headed screw 2 can be easily turned to drive the pair of extrusion plates 22 to move. At the same time, the lever principle can be used to increase the extrusion force of the pair of extrusion plates 22 on the side wall of the elevator shaft. After the support plate 1 is fixed, the slide seat 4 can be slid to a suitable position. As the pointer 41 no longer shakes, the pointer 41 will remain perpendicular to the horizontal plane. At this time, the elevator guide rail can be easily observed. When the force rod 13 is inserted into the socket 12, the top block 5 will push the extension rod 51 upward, so that the extension rod 51 can be pushed upward. The top end of the extension rod 51 is exposed from the top end of the force rod 13. At this time, the extension rod 51 can be partially pulled upward from the inside of the force rod 13, so as to increase the lever arm. When straightening the elevator guide rail, the rubber pad 6 will contact the surface of the elevator guide rail, reducing the rigid contact between the clamping sleeve 16 and the elevator guide rail, thereby reducing the damage to the elevator guide rail. When straightening the elevator guide rail, other straightening tools carried can be hung on the hook 7. When the operator holds the force rod 13 and applies force to straighten the elevator guide rail, the presence of the anti-slip protrusion 8 can reduce the operator's hand slipping.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
