Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more particularly to an elevator shaft. Background Technology

[0002] Currently, the installation of elevators in vertical shafts is still mainly done manually. Due to the increasing labor costs and the risk of accidental injury caused by human negligence during the elevator installation process, with the popularization of automated robots, the robotic automatic installation technology of elevators has gradually become a key research and development focus both inside and outside the industry.

[0003] Due to the wide variety of elevator components and their complex structure, the development of automatic elevator installation robots cannot be accomplished overnight. According to the latest technology survey in the industry, the technology of automatic elevator installation robots is currently limited to the drilling and bolting of expansion bolts for the installation of guide rail brackets in concrete shafts. Because expansion bolt holes in concrete are one-time only and cannot be drilled again within a certain range (due to the risk of concrete cracking), traditional elevator shafts cannot meet the training needs of elevator automatic installation robots to repeatedly drill holes in simulated shafts. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an elevator shaft that can meet the training needs of an automatic elevator installation robot to repeatedly drill holes in a simulated shaft.

[0005] To solve the above-mentioned technical problems, the present invention provides an elevator shaft, comprising: columns, bottom beams, top beams, simulated shaft walls, and structural columns; the columns, bottom beams, and top beams are used to form the external frame of the elevator shaft, and the structural columns are used to form the front entrance of the elevator shaft, the rear support of the shaft, and the door frame; the simulated shaft walls are detachable and replaceable and fixed to both sides of the elevator shaft.

[0006] Preferably, the width of the simulated well wall is 1 / 3 of the column spacing.

[0007] Preferably, the simulated wellbore comprises: The two upright columns, located on either side of the simulated well wall, serve to position and fix the structure. Replaceable concrete blocks for repeated drilling and bolting by the robot; The bottom baffle, middle baffle, and top baffle serve to fix and limit the movement. Friction plates are used to prevent replaceable concrete blocks from loosening under impact; Tighten the bolts to press the friction plate against both sides of the replaceable concrete block.

[0008] Preferably, the replaceable concrete block consists of a concrete body, an embedded steel mesh, and lifting anchors.

[0009] Preferably, the weight of a single replaceable concrete block does not exceed 200 kg.

[0010] Preferably, the width of the replaceable concrete block is 600 mm.

[0011] Preferably, the embedded steel mesh has a two-layer structure, located on the front and back sides of the concrete body respectively.

[0012] Preferably, the bottom of the concrete body has a trapezoidal groove structure.

[0013] Preferably, the friction plate has a grooved structure on the side facing the replaceable concrete block.

[0014] Preferably, the simulated well wall also has a fall-prevention steel wire rope. When installing the simulated well wall, the friction plate is connected to the replaceable concrete block using the fall-prevention steel wire rope before it is lifted. Attached Figure Description

Detailed Implementation

[0016] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0017] like Figure 1As shown in the figure, this specific embodiment provides an elevator shaft 9, including columns 1, bottom beams 2, top beams 3, simulated shaft walls 4, and structural columns 5, 6, 7, and 8. Columns 1, bottom beams 2, and top beams 3 are made of square steel and are used to form the external frame of the shaft. Structural columns 5, 6, 7, and 8 are used to form the front entrance of the elevator shaft, the rear support of the shaft, and the door frame. The simulated shaft walls 4 are detachable and replaceable and are fixed to both sides of the elevator shaft 9. The elevator shaft of this invention is mainly used for training and demonstration of elevator automatic installation robots.

[0018] The width of the simulated well wall 4 is approximately one-third of the spacing between the columns 1, ensuring that personnel outside the well can observe the robot drilling expansion bolt holes and bolting operations from a safe distance.

[0019] like Figure 2 As shown, the simulated well wall 4 includes two side columns 10 for positioning and fixing, a replaceable concrete block 11 for repeated drilling and bolting by the robot, a bottom baffle 12, a middle baffle 13 and a top baffle 14 for fixing and limiting, a friction plate 15 to further prevent the concrete block from loosening under impact, and a top bolt 16 to press the friction plate tightly against both sides of the concrete block.

[0020] The two side columns 10 are made of channel steel; the bottom baffle 12 is welded to the two side columns; the middle baffle 13 is bolted to the two side columns and is detachable for easy replacement of the concrete block; the top baffle 14 uses clamping bolts to apply downward clamping force to prevent the concrete block from jumping upward; the friction pressure plate 15 has a grooved structure on the side facing the replaceable concrete block 11 to increase local pressure. The width of the replaceable concrete block 11 is approximately 600mm, simulating the width range required for elevator guide rail bracket installation.

[0021] like Figure 3 As shown, the replaceable concrete block 11 consists of a concrete body 19, an internal steel mesh 18, and lifting anchors 17. The replaceable concrete block 11 is cast in concrete outside the internal steel mesh 18 and the L-shaped lifting anchors 17. To facilitate lifting, the weight of a single replaceable concrete block shall not exceed 200 kg.

[0022] Because the automated installation robot has the function of scanning the internal steel reinforcement of concrete and automatically avoiding steel reinforcement when drilling, in order to test this function, the embedded steel reinforcement mesh 18 has a two-layer structure, located on both sides of the concrete block 19. In this way, the concrete block can be used in both directions.

[0023] The bottom of the concrete body 19 is a trapezoidal groove structure, which allows the concrete blocks to be stacked and combined.

[0024] like Figure 4As shown, during installation, to prevent the friction plates 15 on both sides of the replaceable concrete block 11 from falling off, the friction plates are connected to the concrete block with anti-fall steel wire ropes 20 before being lifted.

[0025] like Figure 5 As shown, the automatic installation robot 21 uses a robotic arm to hold an electric hammer and drill holes in a replaceable concrete block 11 within the elevator shaft structure.

[0026] Compared with existing ordinary concrete shafts, this invention provides a simple and easy-to-deploy structure for the research and development and demonstration of automatic elevator installation robots.

[0027] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
