Description

Technical Field

[0001] This invention relates to the field of construction equipment, and in particular to a novel safe telescopic operating frame. Background Technology

[0002] Working at heights is a common practice on construction sites for interior decoration, high-altitude cleaning, electromechanical pipeline installation, and power maintenance. To ensure safety, various auxiliary equipment, such as ladders, scaffolding, and lifting platforms, are typically used. However, these auxiliary equipment are not only inconvenient to use but also pose certain safety hazards. Existing lifting platforms use scissor arms or telescopic cylinders installed between a movable base and the platform to drive the platform up and down. When encountering uneven ground, the platform is generally left tilted, posing a safety risk. Alternatively, leveling it by placing boards under the movable base is time-consuming and laborious, requiring the carrying or retrieval of these boards.

[0003] Therefore, a new type of safe telescopic operating frame is needed to replace traditional auxiliary equipment and improve work efficiency and safety. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a new type of safe telescopic operating frame.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0006] A novel safety telescopic operating frame includes:

[0007] An operating platform, wherein a rectangular entrance / exit is provided on the operating platform;

[0008] The telescopic ladder has its top hinged to the operating platform at the front of the entrance / exit, and a winch installed at the bottom of the operating platform at the rear of the entrance / exit. The free end of the winch's wire rope is connected to the bottom of the telescopic ladder.

[0009] An electric telescopic rod is installed at each corner of the bottom of the operating platform. The electric telescopic rods can be controlled to extend and retract independently or in conjunction with each other. Each electric telescopic rod is equipped with a caster with a brake at its bottom.

[0010] A fence is installed around the top of the operating platform.

[0011] The telescopic ladder includes a first ladder body, a second ladder body, and a third ladder body. The top of the first ladder body is hinged to the operating platform at the front of the entrance / exit. A first connecting frame is installed at the bottom of the first ladder body. The second ladder body is fitted into the first connecting frame to allow the first ladder body and the second ladder body to be movably connected. A first limiting block is installed on each of the top two sides of the second ladder body to prevent the second ladder body from slipping out of the first connecting frame. A second connecting frame is installed at the bottom of the second ladder body. The third ladder body is fitted into the second connecting frame to allow the second ladder body and the third ladder body to be movably connected. A second limiting block is installed on each of the top two sides of the third ladder body to prevent the third ladder body from slipping out of the second connecting frame.

[0012] The bottom of the third ladder is hinged to a support plate, and the free end of the winch's wire rope is fixed to the support plate with a rope clamp.

[0013] Preferably, the wire rope of the winch is wrapped with a plastic sleeve.

[0014] Preferably, the operating platform is equipped with level bubbles around its perimeter for observing whether the operating platform is level.

[0015] Preferably, an L-shaped mounting plate is installed at the bottom of the electric telescopic rod, and a guide rod is vertically installed at each end of the L-shaped mounting plate. A connecting rod is installed between two adjacent guide rods on the same side of the operating platform, and a guide sleeve that slides with the guide rod is installed at each end of the connecting rod.

[0016] The height of the guide rod is less than the length of the electric telescopic rod when it is in the fully retracted state.

[0017] Preferably, a vertical support screw is screwed onto the L-shaped mounting plate, and a support block is welded to the bottom end of the support screw.

[0018] The operating platform is rectangular.

[0019] The beneficial effects of this invention are:

[0020] An electric telescopic rod is installed at each corner of the bottom of the operating platform. When the ground is flat, the electric telescopic rod is linked to control the electric telescopic cylinder to extend or retract synchronously. When the ground is uneven or sloping, each electric telescopic rod is independently controlled to extend or retract, so that the operating platform is in a horizontal state. This allows construction workers to stand stably on the operating platform to carry out construction operations, ensuring the safety of the workers and adapting to various complex road conditions.

[0021] A telescopic ladder is installed to facilitate construction workers' access to and from the operating platform; a winch is installed so that when the telescopic ladder is not in use, it can be raised by winding it up; when the telescopic ladder is in use, it can be lowered to the ground by unwinding it.

[0022] Install railings around the top of the operating platform to prevent construction workers from falling off. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 7As shown, a new type of safety telescopic operating frame includes an operating platform 1, a telescopic ladder 2, an electric telescopic rod 4, and a barrier 6. The operating platform 1 is rectangular, and the barrier 6 is installed around the top of the operating platform 1.

[0034] The telescopic ladder 2 includes a first ladder body 201, a second ladder body 202, and a third ladder body 203. The top of the first ladder body 201 is hinged to the operating platform 1 on the front side of the entrance / exit 101. A first connecting frame 204 is installed at the bottom of the first ladder body 201. The second ladder body 202 is fitted into the first connecting frame 204, allowing the first ladder body 201 and the second ladder body 202 to be movably connected. A first limiting block 205 is installed on each of the top two sides of the second ladder body 202 to prevent the second ladder body 202 from slipping out of the first connecting frame 204. A second connecting frame 206 is installed at the bottom of the second ladder body 202. The third ladder body 203 is fitted into the second connecting frame 206, allowing the second ladder body 202 and the third ladder body 203 to be movably connected. A second limiting block 207 is installed on each of the top two sides of the third ladder body 203 to prevent the third ladder body 203 from slipping out of the second connecting frame 206.

[0035] The telescopic ladder facilitates the movement of construction workers up and down the operating platform.

[0036] A rectangular entrance / exit 101 is provided on the operating platform 1. The top of the telescopic ladder 2 is hinged to the operating platform 1 in front of the entrance / exit 101. Specifically, two symmetrical hinge blocks are welded to the bottom of the operating platform 1 in front of the entrance / exit 101. The top of the first ladder body 201 is hinged to the hinge blocks through a hinge shaft.

[0037] A winch 3 is installed at the bottom of the operating platform 1 behind entrance 101. The free end of the wire rope 301 of the winch 3 is connected to the bottom of the telescopic ladder 2. Specifically, a support plate 208 is hinged to the bottom of the third ladder body 203, and the free end of the wire rope 301 of the winch 3 is fixed to the support plate 208 with a rope clamp 209.

[0038] When not in use, the telescopic ladder is hoisted upwards by winding it up with a winch; when in use, the telescopic ladder is lowered and supported on the ground by unwinding it with a winch.

[0039] The wire rope 301 of the winch 3 is wrapped with a plastic sleeve 302. The plastic sleeve 302 improves the comfort of construction workers when they are going up and down the telescopic ladder and holding onto the wire rope 301.

[0040] An electric telescopic rod 4 is installed at each corner of the bottom of the operating platform 1. Each electric telescopic rod 4 can be controlled independently or in conjunction with other rods. Specifically, on flat ground, the electric telescopic rods are controlled in conjunction to extend or retract synchronously. On uneven ground or slopes, each electric telescopic rod can be controlled independently to extend or retract, thus keeping the operating platform level. This allows construction workers to stand stably on the platform for operations, ensuring their safety and adapting to various complex road conditions.

[0041] The operating platform 1 is equipped with level bubble 7 on all four sides for observing whether the operating platform 1 is in a horizontal state.

[0042] An L-shaped mounting plate 8 is installed at the bottom of the electric telescopic pole 4. A guide rod 9 is vertically mounted at each end of the L-shaped mounting plate 8. A connecting rod 10 is installed between two adjacent guide rods 9 on the same side of the operating platform 1. A guide sleeve 11, which slides with the guide rod 9, is installed at each end of the connecting rod 10. Through the cooperation of the guide sleeve and the guide rod, when the electric telescopic pole 4 moves independently, the guide rod and the guide sleeve can move relative to each other when the electric telescopic pole 4 rises and falls. The connecting rod 10 improves the stability of the bottom of the electric telescopic pole 4 and prevents it from swaying.

[0043] The height of the guide rod 9 is less than the length of the electric telescopic rod 4 when it is fully retracted, so as to avoid the guide rod 9 from obstructing the complete retraction of the electric telescopic rod 4.

[0044] Each electric telescopic pole 4 is equipped with a braked caster 5 at its bottom end, so that it can be stopped in a construction area for construction.

[0045] A vertical support screw 12 is screwed onto the L-shaped mounting plate 8. A support block 1201 is welded to the bottom end of the support screw 12. When the new safety telescopic operating frame needs to be stopped in a certain place for a long time for construction operations, the support screw 12 is rotated, and the support block 1202 is supported on the ground, improving the stability of the new safety telescopic operating frame.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
