Description

Technical Field

[0001] The utility model relates to the technical field of mixed tower construction, in particular to an auxiliary device for installing the hoisting points of a mixed tower. Background Art

[0002] From the perspective of the existing mixed tower construction technology, there are many difficulties in installing the lifting appliances during the construction of the mixed tower. Workers often violate regulations. Workers directly stand above the pipe wall of the mixed tower to install the lifting appliances, which poses a safety hazard of falling from a height. Even if the suspension safety belts are used, they are often hung low and used high, failing to play the original protective role. If this method of installing the hoisting points is not adopted, the traditional ladders need to be used to install the hoisting points one by one. Workers need to climb up and down the tower once for each installation of the lifting appliance of a hoisting point. Someone needs to hold the ladder when climbing up and down the ladder, and it is easy to slip during the process of climbing up and down the ladder. Installing the lifting appliances is time-consuming and laborious, and the installation efficiency is extremely low. Content of the Utility Model

[0003] In order to solve the above deficiencies in the prior art, the purpose of the utility model is to provide an auxiliary device for installing the hoisting points of a mixed tower. Workers can automatically adjust the installation of the hoisting points while standing on a movable ladder, saving the trouble of climbing up and down the ladder back and forth, effectively improving the efficiency of installing the lifting appliances at the construction site, and at the same time effectively ensuring the personal safety of the on-site construction personnel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that only the parts related to the utility model are shown in the drawings for the convenience of description.

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0024] AsFigures 1-3 As shown in the figure, this embodiment provides an auxiliary device for the installation of the lifting points of the concrete mixing tower, which includes an adjustable slide rail 2 installed on the periphery of the concrete mixing tower 1. A movable ladder 3 is slidably connected to the adjustable slide rail 2, and a safety belt suspension point 10 is arranged on the movable ladder 3. At least two adjustable slide rails 2 are provided. If the height of the concrete mixing tower 1 is too high, the number of adjustable slide rails 2 can be increased when necessary to improve the stability of the movable ladder 3. In addition, the adjustable slide rail 2 can be assembled by arc-shaped slide rails.

[0025] Specifically, a pulley mechanism is installed behind the movable ladder 3. The number of pulley mechanisms is the same as that of the adjustable slide rails 2. The movable ladder 3 is slidably connected to each adjustable slide rail through each pulley mechanism.

[0026] In this embodiment, a movable ladder support 4 is connected behind the movable ladder 3, and the pulley mechanism is connected to the movable ladder support 4. As Figure 4 shown in the figure, the pulley mechanism includes a support seat 5 connected to the movable ladder support 4. A lockable rotating shaft 6 is connected behind the support seat 5, and a rotating pulley 7 is connected to the end of the rotating shaft 6. The rotating pulley 7 can be stuck in the adjustable slide rail.

[0027] Specifically, in each of the adjustable slide rails 2, at least one adjustable slide rail 2 has a slide rail orientation opposite to that of other slide rails, that is, some slide rails are upward and some are downward. In this way, when installing the rotating pulley 7, some pulleys are installed at the upper end of the adjustable slide rail 2, and some pulleys are installed at the lower end of the adjustable slide rail 2. Each pulley cooperates to clamp the upper and lower ends of the adjustable slide rail 2, playing a limiting role on the movable ladder 3 to prevent its movement in the up and down directions and improving the stability of the structure. An I-shaped slide rail arranged horizontally can also be used, and pulleys can be installed at both the upper and lower ends of the slide rail. In addition, in order to further improve the stability, two rotating pulleys 7 can be installed on each mounting seat to increase the stability of the connection between the pulley mechanism and the adjustable slide rail 2.

[0028] An auxiliary pulley 8 that fits the outer side end of the adjustable slide rail 2 is also connected to the support seat 5. The auxiliary pulley 8 rotates along the outer wall of the adjustable slide rail 2 to make the movement of the movable ladder 3 smoother. In addition, two auxiliary pulleys 8 can be installed on each support seat to increase the smoothness of sliding and the stability of the structure. At least one of the auxiliary pulleys 8 is connected to a motor 12, and the motor 12 drives the rotation of this auxiliary pulley 8, thereby driving the movement of the entire movable ladder 3.

[0029] A fixed ladder support 9 is also connected behind the movable ladder 3. The fixed ladder support 9 can be locked with the adjustable slide rail 2 to prevent the left and right movement of the movable ladder 3. Specifically, as Figure 5As shown, in this embodiment, the fixed ladder support 9 includes a connecting shaft connected to the movable ladder 3. A locking block in an approximate C shape is movably connected behind the connecting shaft. The locking block can be sleeved around the adjustable slide rail 2. A locking bolt is threadedly connected to the upper end surface of the locking block. The locking bolt can extend into the slide rail of the adjustable slide rail 2. The fixed ladder support 9 is fixed to the adjustable slide rail 2 by using the locking bolt, thereby preventing the movement of the movable ladder 3. In this embodiment, a fixed ladder support 9 is provided on each of the left and right sides of each pulley mechanism.

[0030] When installing this device, first assemble and fasten the adjustable track around the concrete mixing tower 1. If the height of the mixing tower 1 is too high, the number of adjustable slide rails 2 can be increased when necessary to improve the stability of the movable ladder 3. After fixing the adjustable slide rail 2, adjust the movable ladder support 4 and the fixed ladder support 9 according to the distance between adjacent adjustable slide rails 2 and then fasten them together with bolts to ensure firm installation. Then rotate the rotating shaft 6 to rotate the rotating pulley 7 into the slide rail of the adjustable slide rail 2 and in a state perpendicular to the slide rail, and lock the rotating shaft 6. The auxiliary pulley 8 is attached to the outer end of the adjustable slide rail 2. After this step of installation, since the movable ladder 3 has a certain weight, the movable ladder 3 will not move without starting the motor 12. Workers climb up the ladder and hang the safety belt at the safety belt hanging point 10. Drive the motor 12 to rotate by operating the remote control to move the movable ladder 3 to the position of the hanging point 11 of the designated hanging tool, and then move the locking block backward to sleeve the locking block around the adjustable slide rail 2, and turn the locking bolt downward to screw the locking bolt into the slide rail of the adjustable slide rail 2. It should be noted that when fixing, it is not necessary to fix all the fixed ladder supports 9 to the adjustable slide rail 2. Only the fixed ladder supports 9 at convenient operating positions need to be fixed. Workers stand on the movable ladder 3, and the position of the installation hanging point 11 can be automatically adjusted, saving the trouble of climbing up and down the ladder, reducing physical consumption, and reducing risks.

[0031] Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solution formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in this application.
