Description

Technical Field

[0001] The utility model relates to the technical field of fire ladders, in particular to a machine room-less fire ladder. Background Art

[0002] In the prior art, the traditional emergency rescue procedure for machine room-less elevators is as follows: the control room receives an alarm from the trapped car, and then notifies the maintenance personnel to carry out rescue. The maintenance personnel first observe and confirm the position, speed, and direction of the car, and then carry out rescue.

[0003] When rescuing people in a machine room, it is often necessary to use a fire ladder. The existing fire ladder has a limited height. When rescuing people at a higher place, the fire ladder needs to be stacked. The stability of the fire ladder is poor when it is stacked. In addition, the existing fire ladder only relies on the wall after it is against the wall. Its stability is poor, and it is easy for people to shake when climbing, causing the center of gravity to be unstable and fall. For this reason, we propose a machine room fire ladder. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a machine room-less fire ladder.

[0005] The technical solution adopted by the utility model to solve its technical problems is a machine room-less fire ladder, comprising a fire ladder body and a screw rod, a support mechanism is installed at the rod wall of the screw rod, and the support mechanism is composed of an L-shaped plate, an internal threaded tube, a threaded rod A, a chassis and a rubber pad. The screw rod passes through the L-shaped plate, an internal threaded tube is welded at the plate wall of the L-shaped plate, a threaded rod A is threadedly connected at the inner wall of the internal threaded tube, the other end of the threaded rod A is welded to the chassis, and a rubber pad is adhered to the bottom of the chassis.

[0006] By adopting the above technical scheme, when increasing the stability of the fire ladder body relying on the wall, since a group of symmetrical screw rods are welded on the outer wall of the fire ladder body, a supporting mechanism is installed on the rod wall of the screw rod, and the supporting mechanism is composed of an L-shaped plate, an internal threaded tube, a threaded rod A, a chassis and a rubber pad. Therefore, after the screw rod is passed through the L-shaped plate, a person twists the threaded sleeve so that the threaded sleeve squeezes the L-shaped plate. Since an internal threaded tube is welded on the plate wall of the L-shaped plate, a threaded rod A is threadedly connected on the inner wall of the internal threaded tube. Therefore, after a person twists the chassis, the threaded rod A rotates in the internal threaded tube. After adjusting the position of the threaded rod A in the internal threaded tube, the chassis is allowed to rely on the bottom of the wall for a second time, thereby improving the reliance stability of the fire ladder body.

[0007] Specifically, it also includes a connecting mechanism, and the top of the fire ladder body is equipped with a connecting mechanism.

[0008] By adopting the above technical solution, it is convenient to connect with the external fire ladder through the connecting mechanism.

[0009] Specifically, the connecting mechanism is composed of a sleeve, a connecting plate, a threaded rod B and an extrusion plate. A group of symmetrical connecting plates are installed on the top of the fire ladder body by bolts. A sleeve is welded at the plate wall of one group of connecting plates. The shell wall is threadedly connected to the threaded rod B. The other end of the threaded rod B is connected to the extrusion plate through a bearing.

[0010] By adopting the above technical solution, when connecting the external fire ladder, since a connecting mechanism is installed on the top of the fire ladder body, the connecting mechanism is composed of a sleeve, a connecting plate, a threaded rod B and an extrusion plate. Since a group of symmetrical sleeves are installed on the top of the fire ladder body by bolts, after the external fire ladder is inserted into the sleeve, the threaded rod B is threadedly connected to the shell wall of the sleeve, and the other end of the threaded rod B is connected to the extrusion plate through a bearing, after the threaded rod B is twisted, the extrusion plate squeezes and fixes the external fire ladder, thereby increasing the connection stability between the fire ladders.

[0011] Specifically, a group of symmetrical screw rods are welded to the outer wall of the fire ladder body.

[0012] By adopting the above technical solution, the connecting plate can be conveniently attached to the seat back through the arc groove.

[0013] Specifically, a group of the screw rods are threadedly connected to a threaded sleeve at the rod wall, and the threaded sleeve is located on one side of the L-shaped plate.

[0014] By adopting the above technical solution, the bottom plate and the driving surface are adsorbed and connected and fixed by the suction cup after being adsorbed on the driving surface.

[0015] Beneficial effects of the utility model:

[0016] (1) The machine room-less fire ladder described in the utility model increases the stability of the fire ladder body against the wall. Since a group of symmetrical screw rods are welded to the outer wall of the fire ladder body, a support mechanism is installed at the rod wall of the screw rods. The support mechanism is composed of an L-shaped plate, an internal threaded tube, a threaded rod A, a chassis and a rubber pad. After the screw rod is passed through the L-shaped plate, a person twists the threaded sleeve so that the threaded sleeve squeezes the L-shaped plate. Since an internal threaded tube is welded to the plate wall of the L-shaped plate, and the threaded rod A is threadedly connected to the inner wall of the internal threaded tube, after the person twists the chassis, the threaded rod A rotates in the internal threaded tube. After adjusting the position of the threaded rod A in the internal threaded tube, the chassis is allowed to lean against the bottom of the wall for a second time, thereby improving the stability of the fire ladder body.

[0017] (2) The machine room-less fire ladder described in the utility model, when connecting to an external fire ladder, a connecting mechanism is installed on the top of the fire ladder body, and the connecting mechanism is composed of a sleeve, a connecting plate, a threaded rod B and an extrusion plate. Since a group of symmetrical sleeves are installed on the top of the fire ladder body by bolts, after the external fire ladder is inserted into the sleeve, the shell wall of the sleeve is threadedly connected with the threaded rod B, and the other end of the threaded rod B is connected to the extrusion plate through a bearing, so that after the threaded rod B is twisted, the extrusion plate squeezes and fixes the external fire ladder, thereby increasing the connection stability of the fire ladder.

Since the internal threaded tube 202 is welded to the plate wall of the L-shaped plate 201, the threaded rod A203 is threadedly connected to the inner wall of the internal threaded tube 202. Therefore, after the personnel twists the chassis 204, the threaded rod A203 rotates in the internal threaded tube 202. After adjusting the position of the threaded rod A203 in the internal threaded tube 202, the chassis 204 is allowed to rely on the bottom of the wall for a second time, thereby ensuring the reliance stability of the fire ladder body 1.

[0026] like Figure 1 As shown, a connecting mechanism 5 is also included, and a connecting mechanism 5 is installed on the top of the fire ladder body 1.

Since the internal threaded tube 202 is welded on the plate wall of the L-shaped plate 201, the threaded rod A203 is threadedly connected on the inner wall of the internal threaded tube 202. Therefore, after the person twists the chassis 204, the threaded rod A203 rotates in the internal threaded tube 202, and the threaded rod A203 is adjusted in the internal threaded tube After being positioned in the position inside 202, the chassis 204 makes a secondary support on the bottom of the wall, thereby ensuring the stability of the fire ladder body 1.
