Description

Technical Field

[0001] This application relates to the field of elevator installation technology, and more specifically, to a safety protection device that facilitates elevator installation. Background Technology

[0002] As a crucial vertical transportation tool in modern buildings, the installation efficiency and safety of elevators directly impact the construction cycle and subsequent reliability. Current elevator installation techniques typically require the temporary installation of support frames inside the elevator shaft to support the elevator car and related components for positioning, assembly, and testing. These support frames are then removed after the elevator car installation is complete. This method presents the following significant problems:

[0003] The installation process is cumbersome and inefficient: the erection, fixing and dismantling of the support frame requires a lot of time and is inconvenient to operate due to the limited space in the shaft, which significantly prolongs the overall elevator installation cycle. Summary of the Invention

[0004] In view of this, this application provides a safety protection device that facilitates elevator installation, in order to solve the technical problems of long installation time and inconvenience in the installation of elevator cars in the prior art.

[0005] This application provides a safety protection device that facilitates elevator installation, wherein the safety protection device that facilitates elevator installation includes:

[0006] An elevator shaft has equipment installation cavities in the two side walls at the bottom of the elevator shaft along the width direction, and an elevator car entrance on one side at the bottom of the elevator shaft along the length direction.

[0007] Two sets of movable support mechanisms are respectively installed on both sides of the bottom of the elevator shaft. Each movable support mechanism includes a support beam and a drive motor. The drive motor is installed in the equipment mounting cavity. The support beam is located in the elevator shaft. The output shaft of the drive motor passes through the side wall of the elevator shaft and connects to the corresponding support beam. The drive motor can drive the support beam to rotate to a horizontal position and to rotate to a vertical position. The two outer side walls of the elevator car in the width direction have vertical grooves. When the support beam is in the horizontal position, the elevator car can enter the elevator shaft from the entrance and be supported on each support beam. When the support beam is in the vertical position, the elevator car can move up and down through the support beam. When the elevator car moves up and down through the support beam, the support beam is located in the vertical groove on the corresponding side of the elevator car.

[0008] Furthermore, a row of guide wheels is provided on the support beam along its length. When the support beam is in a horizontal position, the elevator car can enter the elevator shaft from the entrance and be supported on a row of guide wheels on each of the support beams.

[0009] Furthermore, each of the mounting cavities is equipped with a movable support structure. When the support beam is in a horizontal position, the support structure can extend into the elevator shaft and support the bottom of the corresponding support beam.

[0010] Furthermore, the output shafts of the drive motors in the two sets of movable support mechanisms are arranged coaxially along the width direction of the elevator shaft, and the bottom support structures in the two sets of movable support mechanisms are distributed on both sides of the axis of the output shaft of the drive motor along the length direction of the elevator shaft.

[0011] Furthermore, each of the mounting cavities is equipped with a linkage mechanism, which is connected to the output shaft of the drive motor and the bottom support structure in the corresponding mounting cavity. The two side walls in the width direction of the elevator shaft have through channels, which connect the shaft of the elevator shaft to the corresponding equipment mounting cavity. When the drive motor drives the support beam to rotate to a horizontal position, the linkage mechanism drives the corresponding bottom support structure to extend into the shaft of the elevator shaft through the corresponding through channel. When the drive motor drives the support beam to rotate to a vertical position, the linkage mechanism drives the corresponding bottom support structure to retract from the shaft of the elevator shaft through the corresponding through channel.

[0012] Furthermore, a drive gear is mounted on the output shaft of the drive motor. The linkage mechanism includes a first driven gear, a second driven gear, a first bevel gear, a second bevel gear, and a third driven gear. The first, second, and third driven gears are rotatably mounted in the equipment mounting cavity. The rotation axes of the first and second driven gears are parallel to the output shaft of the corresponding drive motor, and the rotation axis of the third driven gear is perpendicular to the output shaft of the corresponding drive motor. The first bevel gear is coaxially connected to the second driven gear, and the second bevel gear is coaxially connected to the third driven gear. The first driven gear meshes with the drive gear, the second driven gear meshes with the first driven gear, and the first bevel gear meshes with the second bevel gear. The bottom support structure includes a rack slidably mounted in the corresponding mounting cavity and a bottom support arm mounted on the rack. The rack meshes with the corresponding third driven gear. The rack can slide to drive the bottom support arm to extend into the elevator shaft to support the bottom of the corresponding support beam or retract from the elevator shaft.

[0013] Furthermore, when the support beam is in a vertical position and the elevator car moves up and down through the support beam, the guide wheel abuts against one side of the corresponding vertical groove wall.

[0014] Furthermore, a speed sensor and an electrically controlled locking mechanism are installed on the support beam. The electrically controlled locking mechanism is connected to the speed sensor. When the speed sensor detects that the speed of the elevator car passing through the support beam is greater than a preset speed, the electrically controlled locking mechanism locks the guide wheel to make the guide wheel stationary.

[0015] Furthermore, an elastic support mechanism is installed at the bottom of the elevator shaft.

[0016] Furthermore, the elastic support mechanism includes a spring seat and a support plate disposed on the spring seat.

[0017] The beneficial effects of the safety protection device for easy elevator installation provided by this invention are as follows:

[0018] Compared to existing technologies, the safety protection device for easy elevator installation provided by this invention has equipment installation cavities in the two side walls of the elevator shaft at its bottom along the width direction, and two sets of movable support mechanisms respectively disposed on both sides of the bottom of the elevator shaft. Each movable support mechanism includes a support beam and a drive motor. The drive motor can drive the support beam to rotate to a horizontal position and to rotate the support beam to a vertical position. Essentially, the elevator shaft has two built-in movable support mechanisms. When installing an elevator car in the elevator shaft, the drive motor can drive the support beam to a horizontal position, and then the elevator car to be installed can be entered into the elevator shaft through the elevator car's entrance and supported on the support beams. Then, the electric... After the elevator car is pushed into the installation position, the installation work begins. This installation work includes connecting the elevator hoist to the elevator car, etc. The support beam provides excellent support and protection for the elevator car, preventing falls. After the elevator car is installed, the elevator hoist drives the elevator car to rise, and then the drive motor drives the support beam to a vertical position. At this time, because the support beam is located in the vertical groove on the corresponding side of the elevator car when the elevator car moves up and down, the support beam will no longer interfere with the up and down movement of the elevator car. Therefore, this safety protection device, which facilitates elevator installation, eliminates the need to carry and disassemble the elevator car support device during elevator car installation, greatly improving the installation efficiency and convenience of the elevator car and saving elevator installation time.

[0019] In a further embodiment, an elastic support mechanism is installed at the bottom of the elevator shaft. When the elevator car falls to the bottom of the elevator shaft, it can be buffered and elastically supported by the elastic support mechanism, thereby improving the safety protection of the elevator car.

[0036] See Figures 1 to 9This application provides a safety protection device that facilitates elevator installation, wherein the safety protection device that facilitates elevator installation includes:

[0037] An elevator shaft 100 has equipment installation cavities 101 in the two side walls along the width direction of the bottom of the elevator shaft 100, and an entrance 102 for an elevator car 200 is provided on one side of the bottom of the elevator shaft 100 along the length direction.

[0038] Two sets of movable support mechanisms are respectively installed on both sides of the bottom of the elevator shaft 100. Each movable support mechanism includes a support beam 2 and a drive motor 1. The drive motor 1 is installed in the equipment installation cavity 101. The support beam 2 is located in the shaft 103 of the elevator shaft 100. The output shaft 6 of the drive motor 1 passes through the side wall of the elevator shaft 100 and is connected to the corresponding support beam 2. The drive motor 1 can drive the support beam 2 to rotate to a horizontal position and to rotate the support beam 2 to a vertical position. The two outer side walls of the elevator car 200 in the width direction have vertical grooves 201. When the support beam 2 is in the horizontal position, the elevator car 200 can enter the shaft 103 of the elevator shaft 100 from the inlet 102 and be supported on each support beam 2. When the support beam 2 is in the vertical position, the elevator car 200 can move up and down through the support beam 2. When the elevator car 200 moves up and down through the support beam 2, the support beam 2 is located in the vertical groove 201 on the corresponding side of the elevator car 200.

[0039] Because the safety protection device for easy elevator installation provided by the present invention has equipment installation cavities 101 in the two side walls along the width direction of the bottom of the elevator shaft 100, and has two sets of movable support mechanisms respectively arranged on both sides of the bottom of the elevator shaft 100, each movable support mechanism includes a support beam 2 and a drive motor 1. The drive motor 1 can drive the support beam 2 to rotate to a horizontal position and drive the support beam 2 to rotate to a vertical position. It is equivalent to the elevator shaft 100 having two sets of movable support mechanisms. When the elevator car 200 needs to be installed in the shaft 103 of the elevator shaft 100, the drive motor 1 can drive the support beam 2 to a horizontal position, and then the elevator car 200 to be installed can be entered into the shaft 103 of the elevator shaft 100 from the inlet 102 and supported on each support beam 2. Then the elevator car 200 can be pushed into the installation position and then... The installation of the elevator car 200 includes connecting the elevator hoist to the elevator car 200 with lifting equipment, etc. The support beam 2 provides excellent support and protection for the elevator car 200 to prevent falls. After the elevator car 200 is installed, the elevator hoist drives the elevator car 200 to rise, and then the drive motor 1 drives the support beam 2 to a vertical position. At this time, since the support beam 2 is located in the vertical groove 201 on the corresponding side of the elevator car 200 when the elevator car 200 moves up and down, the support beam 2 will no longer interfere with the up and down movement of the elevator car 200. Therefore, this safety protection device that facilitates elevator installation does not require carrying and disassembling the device supporting the elevator car 200 during the installation of the elevator car 200, which greatly improves the installation efficiency and convenience of the elevator car 200 and saves elevator installation and construction time.

[0040] According to a preferred embodiment of this application, a row of guide wheels 300 is provided on the support beam 2 along its length direction. When the support beam 2 is in a horizontal position, the elevator car 200 can enter the shaft 103 of the elevator shaft 100 from the inlet 102 and be supported on a row of guide wheels 300 on each support beam 2. The elevator car 200 supported on the guide wheels 300 can be better guided into the installation position of the elevator shaft 100.

[0041] According to one embodiment of this application, when the support beam 2 is in a vertical position and the elevator car 200 moves up and down through the support beam 2, the guide wheel 300 is attached to one side of the corresponding vertical groove 201. In this way, when the elevator car 200 falls to the bottom of the elevator shaft 100, the guide wheel 300 can guide the elevator car 200 well.

[0042] According to a preferred embodiment of this application, a speed sensor (not shown) and an electrically controlled locking mechanism are installed on the support beam 2. The electrically controlled locking mechanism is connected to the speed sensor signal. When the speed sensor detects that the speed of the elevator car 200 passing through the support beam 2 is greater than a preset speed, the electrically controlled locking mechanism locks the guide wheels 300 to make them stationary. Specifically, the electrically controlled locking mechanism can be an electric guide rail 3 installed on the support beam 2, with an arc-shaped long groove 301 installed on each guide wheel 300. The electric guide rail 3 is connected to a plug rod 4. The insert rod 4 is equipped with a pin 5 corresponding to each guide wheel 300. When the speed sensor detects that the speed of the elevator car 200 is greater than the preset speed, it transmits the signal to the electric guide rail 3. The electric guide rail 3 drives the insert rod 4 to move towards the guide wheel 300, so that each pin 5 is inserted into the arc-shaped long groove 301 of the corresponding guide wheel 300. The guide wheel 300 is locked by the pin 5 and cannot rotate, thereby generating friction with one side of the vertical groove 201 of the elevator car 200 that is in contact with the guide wheel 300, so as to decelerate the elevator car 200.

[0043] According to one embodiment of this application, each mounting cavity is equipped with a movable bottom support structure. When the support beam 2 is in a horizontal position, the bottom support structure can extend into the shaft 103 of the elevator shaft 100 and support the bottom of the corresponding support beam 2. When the support beam 2 is in a horizontal position, since it is also supported by the bottom support structure, it can better bear the weight of the elevator car 200 to be installed on it, and play a better role in protecting the elevator car 200 to be installed from falling.

[0044] According to one embodiment of this application, the output shafts 6 of the respective drive motors 1 in the two sets of movable support mechanisms are arranged coaxially and along the width direction of the elevator shaft 100. The bottom support structures of the respective sets of movable support mechanisms are distributed on both sides of the axis of the output shaft 6 of the drive motor 1 along the length direction of the elevator shaft 100. In this way, when each support beam 2 is in a horizontal position, the bottom support structures corresponding to each support beam 2 support the corresponding support beam 2 in a staggered manner along the length direction of the elevator shaft 100. The elevator car 200 to be installed is supported on the two support beams 2. The staggered bottom support structures corresponding to each support beam 2 can form a more uniform and stable support for the two support beams 2, making the overall force (the weight of the elevator car 200) of the two support beams 2 more balanced.

[0045] According to one embodiment of this application, a linkage mechanism is installed in each mounting cavity. The linkage mechanism is connected to the output shaft 6 of the drive motor 1 in the corresponding mounting cavity and the bottom support structure. The two side walls in the width direction of the elevator shaft 100 have through channels, which connect the shaft 103 of the elevator shaft 100 with the corresponding equipment mounting cavity 101. When the drive motor 1 drives the support beam 2 to rotate to a horizontal position, the linkage mechanism drives the corresponding bottom support structure to extend into the shaft 103 of the elevator shaft 100 through the corresponding through channel. When the drive motor 1 drives the support beam 2 to rotate to a vertical position, the linkage mechanism drives the corresponding bottom support structure to extend out of the shaft 103 of the elevator shaft 100 through the corresponding through channel. 3. Retraction: This embodiment cleverly utilizes the power of the drive motor 1 to match the position of the support beam 2 to meet the requirements of the bottom support structure. When the drive motor 1 drives the support beam 2 to rotate in the first direction (e.g., counterclockwise) to a horizontal position, the linkage mechanism allows the corresponding bottom support structure to extend into the shaft 103 of the elevator shaft 100 through the corresponding through channel to support the bottom of the corresponding support beam 2. When the drive motor 1 drives the support beam 2 to rotate in the second direction opposite to the first direction (e.g., clockwise) to a vertical position, the bottom support structure retracts from the shaft 103 of the elevator shaft 100, thus no longer interfering with the lifting and lowering of the elevator car 200 or the support beam 2.

[0046] According to a specific embodiment of this application, a drive gear 7 is mounted on the output shaft 6 of the drive motor 1. The linkage mechanism includes a first driven gear 8, a second driven gear 9, a first bevel gear 10, a second bevel gear 11, and a third driven gear 12. The first driven gear 8, the second driven gear 9, and the third driven gear 12 are rotatably mounted in the equipment mounting cavity 101. The rotation axes of the first driven gear 8 and the second driven gear 9 are parallel to the corresponding output shaft 6 of the drive motor 1, while the rotation axis of the third driven gear 12 is perpendicular to the corresponding output shaft 6 of the drive motor 1. The first bevel gear 10 and the second driven gear 9... The driving gear 9 is coaxially connected, the second bevel gear 11 is coaxially connected with the third driven gear 12, the first driven gear 8 meshes with the driving gear 7, the second driven gear 9 meshes with the first driven gear 8, and the first bevel gear 10 meshes with the second bevel gear 11. The bottom support structure includes a rack 13 that is slidably installed in the corresponding mounting cavity and a bottom support arm 14 provided on the rack 13. The rack 13 meshes with the corresponding third driven gear 12. The rack 13 can slide to drive the bottom support arm 14 to extend into the shaft 103 of the elevator shaft 100 to support the bottom of the corresponding support beam 2 or retract from the shaft 103 of the elevator shaft 100.

[0047] According to one embodiment of this application, an elastic support mechanism is installed at the bottom of the shaft 103 of the elevator shaft 100. When the elevator car 200 falls to the bottom of the shaft 103 of the elevator shaft 100, it can be buffered and elastically supported by the elastic support mechanism, thereby improving the safety protection of the elevator car 200.

[0048] According to a specific embodiment of this application, the elastic support mechanism includes a spring seat 15 and a support plate 16 disposed on the spring seat 15.

[0049] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
