The construction cost of scaffolding construction platforms in large areas at high altitudes is high, the construction cycle is long, and the construction difficulty is high. When pre-embedded steel components are used as support points, it is necessary to increase the time and cost of pre-embedded parts and their installation.

[0018] The utility model proposes a quick locking device for the high construction platform in the trough structure, which can achieve self-adaptation, no need for external auxiliary support, and fast and efficient construction platform support, thereby solving the problems of long construction period, high cost, poor adaptability and great construction difficulty of the aforementioned high construction platform support structure.

[0019] The device comprises a supporting structure 1, a hydraulic power pump 2, a supporting rod 3, and a top block 4. The supporting rod 3 and the top block 4 are four groups.

[0020] The hydraulic power pump 2 is fixedly installed on the supporting structure 1. The piston rod in the hydraulic power pump 2 is connected to the supporting rod 3, and can drive the supporting rod 3 to move forward and backward along the guide rail direction. The top block 4 is installed at the front end of the supporting rod 3 and connected thereto.

[0021] The locking device is composed of a locking support frame 5, a supporting pin shaft 6, a connecting rod 7, a pin shaft 8, a supporting block 9, a flexible friction plate 10, and a preload spring 11. The locking support frame 5, the supporting pin shaft 6, the connecting rod 7, the pin shaft 8, the supporting block 9, the flexible friction plate 10, and the preload spring 11 are four groups.

[0022] The three sides of the support frame 5 are respectively provided with two groups of pin holes, and a support pin 6 is installed in each group of pin holes. On the three sides, one side of the connecting rod 7 is connected with the support pin 6 through a hole, and a pin 8 is installed in the pin hole set on the other side. The pin 8 is respectively installed with the pin holes on the support block 9. The connecting rod can rotate along the pin 6, and the support block 9 can rotate along the pin 8. Through the constraints of the connecting rod and the pin, the support block 9 remains parallel to the support frame and can rotate along the support frame within a certain range to achieve inward or outward movement. The preload spring 11 connects the support frame 5 and the connecting rod 7 to provide preload force for the support block 9. A flexible friction plate 10 is installed on the outer side of the support block 9.

[0023] The angle between the connecting rod 7 and the horizontal direction is α, and the friction coefficient between the flexible friction plate and the inner wall of the groove structure is µ.

[0024] µ ≥ tanα.

[0025] The construction platform is suitable for use in a rectangular trough structure. When in use, the construction platform is placed at a certain height position in the trough structure through external action, and the piston rods of the hydraulic power pumps 2 on the three surfaces move outward, pushing the support rods 3 to move outward along the guide, pushing the top block 4 to move outward, and the top block 4 contacts the inner wall of the trough structure to achieve horizontal positioning of the device.

[0026] Under the action of the preload spring 11, the connecting rod 7 rotates along the pin shaft 6, driving the support block 9 to move outward, and the flexible friction plate 10 contacts the inner wall of the groove structure. The friction force generated by the flexible friction plate 10 and the inner wall of the groove structure is used to fix the support device in the groove structure.

[0027] The operating principle of the utility model is as follows:

[0028] When used in construction, the construction platform is placed on the support frame 5, and the weight of the construction platform is borne by the device. Under the action of gravity, the flexible friction plate 10 is fixedly connected to the support block 9 to keep it in a fixed state. The support frame 5 tends to move downward relative to the connecting rod 7 and the support block 9 connected thereto, and the relative angle between the connecting rod 7 and the support frame 5 tends to increase. The support block 9 tends to continue to move outward. The gravity of the construction platform is transmitted through the connecting rod mechanism, which increases the contact force between the support block 9 and the inner wall of the groove structure, generating a greater friction force. When the friction force is equal to the dead weight of the construction platform, the effect of supporting the construction platform is achieved.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
