[0001] The utility model relates to the technical field of building construction, and specifically relates to a cantilevered stop floor platform for a construction elevator. Background Technique

[0002] With the rapid development of the construction industry, there are more and more super high-rise projects, and the structural forms are becoming more and more complex and changeable. As one of the indispensable vertical transportation equipment in the field of building construction, the safety and applicability of the transportation passage erected between the cage of the construction elevator and the building structure have always been a major problem.

[0003] The existing drawer-type cantilevered unloading platform with the application number CN202321235078.2 includes two main beams, two side guardrails and a front guardrail. The two main beams are connected by reinforcing ribs, and clamping grooves are arranged on the inner walls from left to right. The two side guardrails are respectively installed at the left end of the top of the main beam to prevent building materials from falling off the platform board. The front guardrail is installed at the left end of the side guardrail. In addition, it also includes a support mechanism and a storage mechanism, and the support mechanism is installed at the right end of the upper surface of the main beam.

[0004] Although the existing technology simplifies the installation process of the cantilevered platform through the support mechanism and makes the cantilevered platform easy to install, there are still the following defects: 1. There is no connection with the cage of the construction elevator. When in use, there is only a support mechanism arranged on one side, and the stability is poor during use; 2. The distance between the two side guardrails cannot be adjusted to meet the needs of cargo transportation. When construction workers walk on it alone, the distance between the side guardrails is too wide, and the psychological safety of the user is poor. When transporting large objects, the distance between the side guardrails is too small, and large-volume materials need to be tilted to enter. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a cantilevered stop floor platform for a construction elevator that can adjust the distance between the two side guardrails on both sides.

The output shaft of the driving motor is arranged vertically upward. A driving gear is installed on the output shaft. Long strip tooth plates are engaged on both the front and rear sides of the driving gear. When the driving gear rotates, the two long strip tooth plates move towards or away from each other; one of the long strip tooth plates is fixedly connected to the left side guardrail, and the other long strip tooth plate is fixedly connected to the right side guardrail.

[0008] The utility model adopting the above technical solution, compared with the existing technology, its prominent feature is:

[0009] During use, the driving motor drives the driving gear to rotate, thereby driving the two long strip tooth plates to move towards or away from each other. The two long strip tooth plates drive the two side guardrails to move towards or away from each other, facilitating the adjustment of the distance between the two side guardrails according to the usage requirements.

[0010] Preferably, a further technical solution of the present utility model is:

[0011] Preferably, the axis of the output shaft of the driving motor coincides with the central axis of the bottom plate; one driving motor can drive the two side guardrails to move, reducing the manufacturing cost.

One of the long toothed plates 4 is fixedly connected to the left side guardrail 5, and the other long toothed plate 4 is fixedly connected to the right side guardrail 5.

[0023] When the driving motor 2 is started, it can drive the driving gear 3 to rotate. The driving gear 3 drives the long toothed plates 4 on both sides to move towards or away from each other, and then drives the side guardrails 5 on the left and right sides to move towards or away from each other. When people walk, the distance between the two guardrails 5 can be reduced, which is convenient for people to hold the side guardrails 5 when walking and improves the construction safety. When transporting goods, the distance between the two guardrails 5 can be adjusted to a suitable distance according to the size of the goods. The present utility model can drive the movement of the two side guardrails 5 through one driving motor 2.

[0024] Furthermore, a first installation groove 101 and two second installation grooves 102 are arranged on the bottom plate 1. The second installation grooves 102 are arranged horizontally.

The driving motor 2 and the driving gear 3 are installed in the first installation groove 101, and the two long toothed plates 4 are respectively installed in the second installation grooves 102. The length of the long toothed plate 4 is 0.6 - 0.8 times the length of the second installation groove 102, so that the long toothed plate 4 can move in the second installation groove 102.

[0025] There are also two guiding grooves 103 arranged at intervals on the bottom plate 1. The guiding grooves 103 are arranged parallel to the second installation groove 102. The two guiding grooves 103 are located outside the two second installation grooves 102. Slide rails are arranged in the guiding grooves 103, and sliders are slidably connected to the slide rails. The sliders are fixedly connected to the bottom of the side guardrail 5, providing a guiding function for the side guardrail 5.

[0026] L-shaped overlapping plates 6 are symmetrically arranged on the front and rear sides of the bottom plate 1. The vertical part 601 of the L-shaped overlapping plate 6 is fixedly connected to the bottom plate 1, and the horizontal part 602 is used for overlapping on the cage or building structure. During use, the front L-shaped overlapping plate 6 overlaps on the bottom plate 1 of the cage, and the rear L-shaped overlapping plate 6 overlaps on the Nth floor slab of the building structure.

[0027] To ensure the support stability of this platform, two sets of support mechanisms are provided. The two sets of support mechanisms are respectively arranged on the two L-shaped overlapping plates 6. Each set of support mechanisms includes two support rods 7. The two support rods 7 are respectively arranged at both ends of the horizontal part 602 of the L-shaped overlapping plate 6. When in use, the two front support rods 7 extend out to tightly abut against the top plate of the cage, and the two rear support rods 7 extend out to tightly abut against the (N + 1)th floor slab when in use. Among them, the support rod 7 can use an electric support rod 7, which is more convenient to use.
