Description

Technical Field

[0001] The present invention relates to a guide rail installation device, in particular to a guide rail installation device for installing an elevator guide rail in an elevator shaft. Background Art

[0002] Elevator installation is a high-altitude operation that is often dangerous and prone to accidents such as falling objects and collisions. Therefore, there is already a technology that considers replacing humans with robots for elevator installation.

[0003] For example, patent document CN111148711A discloses an alignment device for aligning guide rails in an elevator shaft of an elevator system, and a method for assembling guide rails in an elevator shaft of an elevator system. The alignment device and method enable efficient and precise assembly or alignment of the guide rails in the elevator shaft. The alignment device is designed to align the guide rails relative to markings on the shaft wall of the elevator shaft, which have at least three spaced-apart points. The alignment device includes an abutment member with a recess having a shape complementary to the running surface of the guide rail, and a direction-finding device designed and arranged to bring the abutment member into a defined position relative to the markings on the shaft wall. The direction-finding device includes a laser device that projects at least three spaced-apart points onto the shaft wall of the elevator shaft. The abutment member and the direction-finding device may together form a single component. Summary of the Invention

[0004] Problems to be solved by the invention

[0005] However, in patent document CN111148711A, the final two steps of guide rail assembly are performed manually by assemblers, resulting in a low level of automation. In particular, in patent document CN111148711A, the guide rail mounting process is not automated. Because the lifting platform is hoisted within the hoistway, the installation of the elevator guide rails requires drilling holes in the wall, which can cause significant vibrations and significantly affect the position and posture of the installation robot. Therefore, automated guide rail installation by a robot is difficult.

[0006] Therefore, an object of the present invention is to provide a guide rail installation device capable of automatically installing an elevator guide rail in a hoistway.

[0007] Technical means to solve the problem

[0008] In order to achieve the above-mentioned purpose, one embodiment of the present invention is a guide rail installation device for installing the guide rail of an elevator into an elevator shaft, characterized in that it comprises: a plurality of first support devices, which have support rods that can extend outward from the side of the guide rail installation device, are fixed to the upper surface of the top plate of the guide rail installation device, and are symmetrically distributed on the upper surface of the top plate; a working robot, which is set on a tool setting table fixed to the lower part of the guide rail installation device, and is used to fix the guide rail in the elevator shaft; a guide rail holding device, which is set on the side of the guide rail installation device different from the side where the support rods extend outward, and has at least two, respectively. The tool setting table and the guide rail mounting device are connected to each other through the support rods of the first supporting device and the tool setting table, respectively, and the support rods are connected to each other through the support rods of the first supporting device and the tool setting table, respectively. The tool setting table and the guide rail mounting device ...

[0009] Effects of the Invention

[0010] According to the present invention, the guide rail installation device can be temporarily and reliably fixed within the hoistway via multiple support devices. Therefore, while the working robot is installing the guide rails, the position and posture of the working robot can be maintained unchanged. Furthermore, the guide rail installation device can be repositioned within the hoistway via the multiple support devices and the lifting column. This allows for automatic and precise installation of guide rails within the elevator hoistway, reducing manual overhead work. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a three-dimensional diagram of the guide rail installation device of the present invention.

[0012] Figure 2 It is a front view of the guide rail installation device of the present invention. DETAILED DESCRIPTION

[0013] The following is an explanation of the embodiments of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of the present invention are limited to this embodiment. On the contrary, the purpose of introducing the present invention in conjunction with the embodiment is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0014] Figure 1 is a perspective view of the guide rail installation device of the present invention, Figure 2 It is a front view of the guide rail installation device of the present invention.

[0015] like Figure 1 As shown, the guide rail installation device of the present invention includes a support device 1, a guide rail holding device 2, a bracket holding device 3, a lifting column 4, a working robot 5, a control unit 6, a tool setting table 7, and a material storage area 8.

[0016] The support device 1 has a support rod that can extend outward from the side of the guide rail mounting device. The support rods of the multiple support devices 1 are arranged in parallel with each other, and the extension direction of the support rod on the left is opposite to the extension direction of the support rod on the right. The multiple support devices 1 are fixed to the upper surface of the top plate of the guide rail mounting device and the lower surface of the tool setting table 7, and are distributed symmetrically on the upper surface of the top plate and on the lower surface of the tool setting table 7. In addition, although Figure 1 It is shown in the figure that a support device 1 is also fixed on the lower surface of the tool setting table 7. However, the support device 1 can also be provided only on the upper surface of the top plate of the guide rail mounting device without providing the support device 1 on the lower surface of the tool setting table 7. The guide rail mounting device can also be reliably temporarily fixed in the shaft by providing the support device 1 only on the upper surface of the top plate of the guide rail mounting device. Obviously, providing the support device 1 on both the upper surface of the top plate of the guide rail mounting device and the lower surface of the tool setting table 7 can more reliably temporarily fix the guide rail mounting device in the shaft. In addition, for the purpose of distinction, in the present invention, the multiple support devices 1 fixed on the upper surface of the top plate of the guide rail mounting device are referred to as first support devices, and the multiple support devices 1 fixed on the lower surface of the tool setting table 7 are referred to as second support devices.

[0017] The support device 1 uses a stepper motor or other device to extend a support rod outward from the side of the guide rail mounting device. The extension speed and extension amount of the support rod are controlled, and the extension amount of the support rod is maintained when the guide rail mounting device is temporarily fixed in the hoistway. When the guide rail installation operation is completed, the support device 1 retracts the support rod, releasing the guide rail mounting device.

[0018] The guide rail retaining device 2 is disposed on a side of the guide rail mounting device that is different from the side from which the support rod extends, thereby preventing interference with the support device 1. Furthermore, in the present invention, at least two guide rail retaining devices 2 are provided, one below the top plate and one below the tool setting table 7, for retaining the guide rail 9. By retaining the guide rail 9 with at least two guide rail retaining devices 2, the guide rail 9 can be reliably retained, and its position can be accurately determined during installation, facilitating installation of the guide rail 9 by the working robot 5 described later.

[0019] In addition, in the present invention, it is preferable that the guide rail holding device 2 can only move on the horizontal plane. Thereby, the position deviation of the guide rail holding device 2 caused by the weight of the guide rail 9 can be prevented.

[0020] In addition, in the present invention, preferably, the plurality of guide rail holding devices 2 each have a holding portion for holding the guide rail, and the tops of the plurality of holding portions are located in the same vertical plane. Thus, the guide rail 9 can be held in the same vertical plane to prevent position deviation of the guide rail 9.

[0021] The bracket retaining devices 3 are provided corresponding to the guide rail retaining devices 2 and are disposed below each of the guide rail retaining devices. They are used to retain the brackets that secure the guide rails. That is, in the present invention, a bracket retaining device 3 is provided below each guide rail retaining device 2. Thus, by having at least two bracket retaining devices 3 retain the brackets that secure the guide rails 9, the brackets can be reliably held, allowing accurate positioning of the brackets during installation, facilitating bracket installation by the working robot described later.

[0022] Lifting columns 4 are fixedly connected to the top plate and the tool platform 7 and can be adjusted in length, that is, the distance between the top plate and the tool platform 7 can be changed. There are at least four lifting columns 4, which are parallel to each other and form the four vertical sides of the lateral outer surface of the guide rail installation device. Thus, the lifting columns 4, the top plate, and the tool platform 7 form the outer frame of the guide rail installation device.

[0023] In addition, if Figure 1In the present invention, preferably, each of the plurality of lifting columns comprises a frame and a lifting column housed within the frame, and the lifting columns are capable of vertical extension and retraction relative to the frame. This allows for free adjustment of the vertical position of the working robot 5, facilitating the fixing of the working robot 5 to the guide rail. Furthermore, in the present invention, preferably, when the plurality of lifting columns are extended or retracted vertically, they move simultaneously and parallel to each other with the same amount of movement. This allows for smooth adjustment of the distance between the top plate and the tool setting platform 7, preventing tilting of the top plate and the tool setting platform 7.

[0024] In addition, the guide rail installation device can change its position in the shaft through the support device 1 and the lifting column 4. Specifically, after the guide rail installation is completed at a certain place in the shaft, for example, the first support device retracts the support rod, the second support device keeps the guide rail installation device in a fixed state, and the lifting column of the lifting column 4 retracts into the frame. Subsequently, the first support device extends the support rod to keep the guide rail installation device in a fixed state, the second support device retracts the support rod, and the lifting column of the lifting column 4 extends from the frame. Repeating this action, the guide rail installation device can be lowered in the shaft. Conversely, the guide rail installation device can be raised in the shaft. In this way, the guide rails can be automatically installed in the entire shaft. Of course, it is also possible to install a lifting rope on the guide rail installation device and manually adjust the upper and lower positions of the guide rail installation device in the shaft.

[0025] The working robot 5 is mounted on a tool mounting platform 7 fixed to the lower portion of the guide rail mounting device and is used to secure the guide rail in the elevator shaft. For example, an arm robot with six or more axes is used as the working robot 5 .

[0026] A control unit 6 is mounted on a tool placement platform 7 and controls the operation of the guide rail installation device. Specifically, the control unit 6 controls the extension and retraction of the support rod of the support device 1, controls the movement of the guide rail holding device 2 to position the guide rail 9 in the appropriate position, controls the extension and retraction of the lifting column 4, and controls the operation of the working robot 5 to install the guide rail 9 in the hoistway.

[0027] The present invention also includes a material storage area 8, which is surrounded by the tool setting table and the lifting column. Located above the tool setting table 7, the material storage area 8 is used to store bolts and other materials used in installing the guide rails 9, making them easily accessible to the working robot 5.

[0028] Thus, according to the present invention described above, the guide rail installation device can be temporarily and reliably fixed within the hoistway via the multiple support devices 1. Therefore, when the working robot 5 installs the guide rail 9, the position and posture of the working robot 5 can be maintained unchanged. Furthermore, the guide rail installation device can be repositioned within the hoistway via the multiple support devices 1 and the lifting column 4. This allows for accurate and automated installation of guide rails within the elevator hoistway, reducing manual overhead work.

[0029] While the embodiments of the present invention have been described above, the embodiments are intended to be illustrative only and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. These embodiments and their variations are intended to be within the scope and spirit of the invention and are also intended to be within the scope of the invention set forth in the claims and their equivalents.
