The lock shaft can be inserted into the shaft seat.

In order to be able to explain the structure and working principle of the present application in more detail, the whole device will be described in detail with reference to fig. 1-3.

As shown in figures 1-3, the anti-moving device for the construction elevator stop floor is characterized in that a starting rod 2 is welded on a cage door 1 of an original vertical movable door. The side surface of the cage door 1 is fixed by a bolt mounting support seat 11, one end of the slide rail 3 is fixed on the support seat 11, and the other end of the slide rail 3 is fixed with a main beam of a large frame 13 of the cage after being leveled by an adjusting block, and the slide rail 3 is ensured to be in a horizontal position. A movable locking shaft 7 is placed in the sliding rail 3, a shaft seat 8 is installed in a matching mode through the movement of the locking shaft 7, and the shaft seat 8 is well fixed with the other main beam of a large frame 13 of the suspension cage after being leveled through an adjusting block 14. The long connecting rod 4 is respectively hinged with one end of the starting rod 2 and one end of the lock shaft 7 through pin shafts, the lock shaft 7 can move in the sliding rail 3, and the lock shaft 7 extends into the shaft seat 8 along with the opening of the door and retracts into the original position along with the closing of the door. A fixed seat 12 is installed on the side face of the suspension cage 10 through bolts, and the middle of the long connecting rod 4 is hinged with one end of the short connecting rod 6 through a pin shaft 5. The other end of the short connecting rod 6 is hinged on the fixed seat 12 through a pin shaft so as to ensure that the long connecting rod 4 does not have a movement dead point along with the movement of the cage in the opening and closing processes.

The operation method comprises the following steps: after the cage operation reaches each layer and stops the layer, the driver up opens the process of cage door, and actuating lever 2 goes upward along with the cage door, and simultaneously, actuating lever 2 drives the one end of long connecting rod 4 through round pin axle 5 and upwards moves, and the other end of long connecting rod 4 drives lock axle 7 through round pin axle 5 and stretches out right along the horizontal direction simultaneously, until emboliaing in axle bed 8, makes the cage by slide rail 3, lock axle 7, axle bed 8 firmly restrict in the guide rail frame of immobilization. The middle part of the long connecting rod 4 drives the short connecting rod 6 to rotate around the fixed seat 12 through the pin shaft 5, so that the movement component force of the long connecting rod 4 towards the movement direction is increased, and the movement dead point is prevented. Therefore, the safety protection effect of preventing accidental movement during floor stopping operation of the construction elevator without occupying the space of the top of the cage is realized. After stopping the floor operation and accomplishing, the driver down closes the process of cage door, and actuating lever 2 is down along with the cage door, and simultaneously, actuating lever 2 drives the one end of long connecting rod 4 through round pin axle 5 and moves down, and the other end of long connecting rod 4 drives lock axle 7 through round pin axle 5 simultaneously and withdraws left along the horizontal direction, and the normal operating can be got back to lock axle 7 until lock axle 7. Because the invention is implemented on the basis of the existing electromechanical interlocking technology of the cage door, after the cage door is opened, the control circuit is broken, and the cage can not operate. When the suspension cage is actually used, if the lock shaft 7 extends out and meets the blockage of the guide rail frame rod piece, the suspension cage can move up and down in a inching mode to avoid; special cases may also be possible in which the connection between the actuating lever 2 and the pin 5 is released and temporarily avoided.

Example two

Because the guide rail frame 9 is a tower-shaped structure formed by mutually fixing or welding square pipes or angle steels through bolts, and the square pipes or angle steels for connection are arranged on the guide rail frame in the transverse direction, the longitudinal direction and the oblique direction, the positions of the guide rail frame 9 corresponding to different floors are not necessarily suitable for allowing the lock shaft 7 to pass through the whole space of the guide rail frame 9 and be accurately inserted into the shaft seat 8. Of course, some standard sections are used, but the same problem exists in the standard sections. Sometimes, when a certain floor stops, the transverse square tube or the angle steel just blocks the lock shaft 7. In order to solve the above problem, optimization is performed on the basis of the first embodiment. As shown in fig. 4, in addition to the first embodiment, three slide rails 3 are added, and the three slide rails 3 are respectively arranged in parallel. Similarly, the number of the long connecting rods 4 is three, the three long connecting rods correspond to the three sliding rails 3 respectively, and the three long connecting rods 4 are arranged in parallel and are hinged to the short connecting rods 6 respectively. The other ends of the three long connecting rods 4 are respectively hinged with the starting rod 2. Each slide rail 3 is provided with a lock shaft 7; one end of the lock shaft 7 is connected to the long link 4 by a spring 70. The spring 70 is a compression spring. A sliding block 71 is arranged in the sliding rail 3 in a sliding mode, and the inner side of one end of the long connecting rod 4 is hinged to the sliding block 71. In a further departure from the first embodiment, the length of the locking shaft 7 is smaller than the distance of movement of the slide 71 from one end point to the other in the slide rail 3. In order to facilitate locking and sliding, the cross section of the lock shaft 7 is of a rectangular structure.

The operation method comprises the following steps: when the cage runs to reach each layer and stops, a driver opens the cage door upwards, the starting rod 2 moves upwards along with the cage door, meanwhile, the starting rod 2 drives one end of 3 long connecting rods 4 to move upwards through a pin 5, the long connecting rods 4 are hinged with the short connecting rods 6, the bottom ends of the short connecting rods 6 are hinged with the fixed seat 12, the end parts of the long connecting rods 4 are hinged with the sliding blocks 71 located in the sliding rails 3, when the starting rod 2 rises, one end of the long connecting rods 4 also moves rightwards along the sliding rails 3, and therefore the spring 70 and the lock shaft 7 are driven to move towards the direction of the guide rail frame 9. One part of the locking shaft 7 extends into the guide rail frame 9, the locking shaft and the guide rail frame 9 form an interlocking structure, and the 3 locking shafts 7 can stably lock the suspension cage on the guide rail frame 9. The distance between the 3 lock shafts 7 is larger than the width of the square pipe and the angle steel which form the guide rail frame 9, so that the situation that at least two of the 3 lock shafts can extend out if being just hindered by the square pipe and the angle steel when the floor is leveled can be ensured, the other lock shaft is blocked by the square pipe and the angle steel, and the spring 70 is compressed and cannot extend out. This ensures very good and reliable stopping of the cage. In addition, because one of the lock shafts 7 is compressed and can not extend, when the cage is dropped under a special emergency condition, for example, one or two lock shafts fail, the other lock shaft can be separated from the barrier and extend when the cage slides down due to the pressure action of the spring and is clamped in the guide rail frame, so that the emergency locking is realized, and the safety of the cage is ensured at multiple angles.

This application is fixed on cage one side and is provided with supporting shoe and fixing base. The fixed 3 slide rails that are provided with of one end of supporting shoe, every slide rail is internal to be provided with the slider in the slidable, and three long connecting rods are articulated with the slider respectively, slider and spring one end fixed connection, the spring other end and lock axle fixed connection. The other ends of the long connecting rods are hinged with the starting rods respectively, the three long connecting rods are arranged in parallel and hinged with the short connecting rods respectively, and the other ends of the short connecting rods are hinged on the fixed seat through pin shafts. The three locking shafts can extend out and insert into the guide rail frame along with the opening of the cage door through the structure, if the locking shaft touching the obstacle stops extending out under the action of the compression of the spring, other locking shafts, the guide rail frame, the roller assemblies and the like form layer stopping anti-moving protection and can reset along with the closing of the cage door, so that the problem that the obstacle of the guide rail frame (standard knot) is encountered when the locking shaft extends out is solved.
