[0024] The following will further describe the present utility model in detail Figures 1 - 7 in conjunction with the appended

[0025] Please refer to Figures 1 - 7, An embodiment of a steel frame hoistway for an additional elevator provided by the present utility model: A steel frame hoistway for an additional elevator includes a column 1. A cross bar 2 is arranged on one side of the column 1. After the cross bar 2 is connected to the column 1, a frame body is formed. The stability of the column 1 is enhanced through the cross bar 2. The top end of the column 1 is fixed with a top plate 3 by bolts. The top plate 3 is used to ensure the stability of the column 1; a connecting mechanism 4 is arranged inside the column 1. The connecting mechanism 4 is used to conveniently connect the column 1 and the cross bar 2 and reinforce the column 1 and the cross bar 2 after connection. The connecting mechanism 4 includes a clamping block 401 sleeved inside the column 1. A first clamping groove 201 is opened at the bottom end of the cross bar 2. The first clamping groove 201 matches the clamping block 401. One end of the column 1 is sleeved with a clamping rod 410. A second clamping groove 202 is opened at the bottom end of the cross bar 2. The second clamping groove 202 is located at one end of the first clamping groove 201. The second clamping groove 202 matches the clamping rod 410. The clamping block 401 is engaged with the first clamping groove 201, and the second clamping groove 202 is engaged with the clamping rod 410, thereby facilitating the connection and fixation of the column 1 and the cross bar 2 and improving the stability of the column 1 and the cross bar 2 after connection; the connecting mechanism 4 further includes a first spring 402 fixedly connected to the bottom end of the clamping block 401. The bottom end of the first spring 402 is fixedly connected to the inner wall of the column 1. The top end of the clamping block 401 is inclined. A placement groove 101 is opened on one side of the column 1. The clamping block 401 is located inside the placement groove 101. The first spring 402 is used to provide a restoring force for the vertical movement of the clamping block 401, and the top end of the clamping block 401 is set to be inclined to facilitate the engagement of the clamping block 401 with the first clamping groove 201;

[0026] A moving plate 403 is sleeved inside the clamping block 401. The moving plate 403 is located at one end of the clamping block 401. A connecting rod 404 is fixed to the bottom end of the moving plate 403 by bolts. One end of the moving plate 403 extends into the placement groove 101. When the cross bar 2 moves towards the inside of the placement groove 101, it can squeeze the moving plate 403 to move. The movement of the moving plate 403 can drive the connecting rod 404 to move; a limiting column 4031 is sleeved inside the inner wall of the moving plate 403. Both sides of the limiting column 4031 are fixedly connected to the inner wall of the column 1 by bolts. The limiting column 4031 is used to support the moving plate 403 and ensure the stability of the horizontal movement of the moving plate 403; a second spring 4032 is fixedly connected to one side of the moving plate 403. The second spring 4032 is sleeved on the outer wall of the limiting column 4031. The other side of the second spring 4032 is fixedly connected to the inner wall of the column 1. The second spring 4032 is used to ensure the initial state of the moving plate 403, thereby facilitating the subsequent horizontal movement of the cross bar 2 to squeeze the moving plate 403 to move;

[0027] One end of the connecting rod 404 is fixed with an extrusion block 405 through a bolt. One end of the extrusion block 405 is in contact with a moving seat 406. One end of the moving seat 406 is set to be inclined. One end of the moving seat 406 is fixedly connected with a third spring 4061. The other end of the third spring 4061 is fixedly connected with the inner wall of the column 1. The third spring 4061 is used to ensure the initial position of the moving seat 406. The horizontal movement of the connecting rod 404 can drive the extrusion block 405 to move. The movement of the extrusion block 405 can extrude one end of the moving seat 406, and then drive the moving seat 406 to move horizontally. One end of the moving seat 406 is fixed with a rack 407 through a bolt. The rack 407 is located on one side of the third spring 4061. The top of the rack 407 is engaged with a spur gear 408. One side of the spur gear 408 is welded with a rotating rod 409. The outer wall of the rotating rod 409 is fixedly connected with a clamping rod 410 through a bolt. The rotating rod 409 is fixedly connected with the inner wall of the column 1 through a bearing. The horizontal movement of the moving seat 406 can drive the rack 407 to move. The movement of the rack 407 drives the spur gear 408 to rotate. The rotation of the spur gear 408 can drive the rotating rod 409 and the clamping rod 410 to rotate. The bottom end of the rack 407 is sleeved with a slide rail 4071. The bottom end of the slide rail 4071 is fixedly connected with the inner wall of the column 1 through a bolt. The slide rail 4071 is used to support the rack 407 and ensure the stability of the horizontal movement of the rack 407. One end of the column 1 is provided with a storage groove 102. The storage groove 102 matches the rotation trajectory of the clamping rod 410. The storage groove 102 is used to store the clamping rod 410.

[0028] Working principle: First, when connecting the column 1 and the cross bar 2, align the cross bar 2 with the placement groove 101 on one side of the column 1, and then push the cross bar 2 into the placement groove 101. The cross bar 2 moves and presses the top of the clamping block 401. The clamping block 401 moves downward, and the first spring 402 is stressed and compressed. When the cross bar 2 completely moves into the placement groove 101, the first card slot 201 and the clamping block 401 are at the same vertical position. At this time, the first spring 402 returns to its original state and drives the clamping block 401 to move back. The clamping block 401 moves back and engages with the first card slot 201. At this time, the column 1 and the cross bar 2 are fixedly connected.

[0029] Meanwhile, when the cross bar 2 moves towards the inside of the placement groove 101, it squeezes the moving plate 403 to move towards the side close to the second spring 4032. The movement of the moving plate 403 drives the connecting rod 404 to move, the movement of the connecting rod 404 drives the extrusion block 405 to move, and the extrusion block 405 moves and squeezes the inclined surface at one end of the moving seat 406, thereby pushing the moving seat 406 to move towards the end close to the spur gear 408. The movement of the moving seat 406 drives the rack 407 to move, the movement of the rack 407 drives the spur gear 408 to rotate, the rotation of the spur gear 408 drives the rotating rod 409 to rotate, and the rotation of the rotating rod 409 drives the clamping rod 410 to rotate. When the first clamping groove 201 is engaged with the clamping block 401, the clamping rod 410 rotates out of the inside of the storage groove 102 and rotates into the inside of the second clamping groove 202. At this time, a triangle is formed among the clamping rod 410, the column body 1 and the cross bar 2;

[0030] Finally, through the setting of the clamping block 401 and the first clamping groove 201, it is convenient to quickly connect and fix the column body 1 and the cross bar 2. Through the setting of the placement groove 101, it is convenient to accurately dock the clamping block 401 and the first clamping groove 201. Compared with the traditional fixing method with multiple bolts, the connection efficiency of the column body 1 and the cross bar 2 is improved, and at the same time, the workload of the staff is reduced. During the connection and fixing process of the cross bar 2 and the column body 1, the horizontal driving force of the cross bar 2 can drive the clamping rod 410 to rotate through mechanical transmission. The clamping rod 410 rotates and is engaged with the second clamping groove 202, thereby forming a triangle among the column body 1, the cross bar 2 and the clamping rod 410, further improving the stability after the connection of the column body 1 and the cross bar 2.
