Description

Technical Field

[0001] This invention relates to the field of vertical elevators, specifically to a machine room elevator that facilitates manual rescue operations. Background Technology

[0002] The elevator was operated by two people working together during the rescue operation.

[0003] Two people go to the machine room. First, they need to disconnect the main power supply. One person places the handwheel onto the motor shaft and firmly grips it to prevent the elevator from sliding when the brake is released. The other person uses the brake wrench to release the brake. Then, they turn the handwheel to move the elevator downwards, check the floor markings on the traction rope, and release the passengers from the elevator car once the nearest floor is reached. Floor markings are usually painted on the traction rope.

[0004] This approach has the following obvious drawbacks:

[0005] 1. After prolonged use, the paint on elevators may peel off, making it difficult for rescuers to determine the turning distance and accurately stop the elevator on the nearest floor.

[0006] 2: When the car has moved too far down, it needs to be readjusted upwards, which greatly reduces the difficulty of operation for rescue personnel. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention provides a machine room elevator that facilitates manual rescue, thereby solving at least one of the above-mentioned problems.

[0008] A machine room elevator that facilitates manual rescue includes a car, a moving block, a locking device, guide rails, and a triggering mechanism;

[0009] The movable block is movably disposed on the top of the car and includes an inclined surface protruding from the top of the car, the inclined surface having a force-bearing inclined surface;

[0010] The locking device is fixedly connected to the top of the car and includes a pin driven by the moving block;

[0011] The guide rail is provided with a socket for engaging with the pin;

[0012] The triggering mechanism includes a trigger block and a vertical rail; the vertical rail is located on the side of the inclined section and extends from the bottom of the shaft to the machine room, and the trigger block, which can be released downward, is provided at the part of the vertical rail located in the machine room;

[0013] The trigger block, after being released, moves downward along the vertical rail and presses against the force-bearing inclined surface, which includes a force-applying inclined surface that interacts with the force-bearing inclined surface, thereby causing the moving block to move by acting on the force-bearing inclined surface.

[0014] Preferably, the locking device further includes a pin holder for mounting the pin, through which the pin passes.

[0015] Preferably, the locking device further includes a spring mounting plate disposed on the pin and a return spring connecting the spring mounting plate and the pin seat.

[0016] Preferably, the pin is connected to the movable block via a connecting arm.

[0017] Preferably, it also includes a release device;

[0018] The release device includes a drum located in the machine room, a connecting rope wound around the drum and connected to the trigger block, and a guide wheel located in the machine room, with the connecting rope wound around the guide wheel.

[0019] Preferably, the top of the car is also provided with a limiting block for limiting the moving distance of the moving block.

[0020] Preferably, there are two moving blocks and locking devices, which are symmetrically arranged on the top of the car, and each moving block is provided with a corresponding triggering mechanism.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. This invention eliminates the traditional method of marking floors on the traction rope and using these markings for rescue operations. Instead, it incorporates a triggering mechanism, a moving block, a locking device, and guide rails with insertion holes. This eliminates the risk of floor markings falling off. During the downward movement of the elevator car, the turning distance can be precisely determined, allowing the elevator to stop accurately and quickly at the nearest floor, improving rescue efficiency. The pin automatically inserts into the insertion hole during the downward movement of the car, eliminating the problem of excessive downward movement and the need to readjust the car's position, greatly reducing the operational difficulty for rescue personnel. After the car turns, because the pin is inserted into the insertion hole, it prevents the car from falling again, increasing the safety of personnel escaping.

[0023] 2: This invention utilizes a reel to allow the trigger block to move slowly downwards and press smoothly onto the inclined surface, preventing a violent impact that could cause greater panic. Furthermore, after the rescue is completed, the trigger block can be directly returned to the computer room using the reel, making the operation simple and convenient. Attached Figure Description

[0026] Figure 3 This is a schematic diagram of the car's installation.

[0027] Figure 4 for Figure 2 Enlarged view of section B in the middle. Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example: Figure 1-4 As shown, a machine room elevator that facilitates manual rescue includes a car 1, a moving block 2, a locking device 3, a guide rail 4, and a triggering mechanism 5.

[0030] The movable block 2 is movably disposed on the top of the car 1. The top of the car 1 is provided with a slide rail 2-0 for mounting the movable block 2. The movable block 2 includes an inclined surface 21 that protrudes beyond the top of the car 1. Considering that the space behind the hoistway is relatively large, the inclined surface 21 preferably protrudes rearward from the top of the car 1. The inclined surface 21 has a force-bearing inclined surface 211. The top of the car 1 is also provided with a limiting block 2-1 for limiting the moving distance of the movable block 2.

[0031] The locking device 3 is fixedly connected to the top of the car 1, and includes a pin 31 driven by the moving block 2 and a pin seat 32 for installing the pin 31. The pin seat 32 is fixedly connected to the top of the car 1, and the pin 31 can be connected to the moving block 2 through the connecting arm 3-0.

[0032] The guide rail 4 is provided with a socket for engaging with the pin 31;

[0033] The triggering mechanism 5 includes a trigger block 51 and a vertical rail 52. The vertical rail 52 is located on the side of the inclined section 21 and extends from the bottom of the shaft into the machine room. The machine room is provided with a mounting bracket 01 for installing the vertical rail 52. The trigger block 51, which can be released downward, is provided at the position of the vertical rail 52 in the machine room. The bottom of the machine room is provided with a through hole 53 for the trigger block 51 to pass through. Releasing the trigger block 51 in the machine room is simple and convenient.

[0034] After being released, the trigger block 51 moves downward along the vertical rail 52 and presses against the force-bearing inclined surface 211. The trigger block 51 includes a force-applying inclined surface 511 that interacts with the force-bearing inclined surface 211. When the trigger block 51 presses against the force-bearing inclined surface 211, the force-applying inclined surface 511 acts on the force-bearing inclined surface 211, causing the moving block 2 to move under the gravity of the trigger block 51.

[0035] In this embodiment, before real-time tug-of-war rescue, the elevator first releases the trigger block 51. The trigger block 51 moves downward along the vertical rail 52 and presses against the force-bearing inclined surface 211. Furthermore, by acting on the force-bearing inclined surface 211, the moving block 2 moves under the gravity of the trigger block 51, thereby pushing the pin 31. The pin 31 presses against the guide rail surface. When tug-of-war is performed, as the car 1 moves downward, the pin 31 also moves downward on the guide rail surface. When the pin 31 moves to align with the socket, the pin 31 is pushed into the socket due to the lack of obstruction. At this time, the car 1 is flush with the floor level, completing the tug-of-war.

[0036] It is evident that this machine room elevator has the following advantages:

[0037] 1. The traditional method of marking floors on the traction rope and using these markings for rescue operations has been eliminated. Instead, a structure combining a triggering mechanism, moving blocks, locking devices, and guide rails with insertion holes has been implemented. This eliminates the risk of floor markings falling off, and the elevator can accurately determine the turning distance during the downward movement of the car, allowing the elevator to stop precisely and quickly at the nearest floor, thus improving rescue efficiency.

[0038] 2: The latch automatically inserts into the socket during the car's descent, eliminating the problem of the car needing to be readjusted upwards due to excessive descent, thus greatly reducing the operational difficulty for rescue personnel.

[0039] 3: After the car is turned around, the latch is inserted into the socket, which can prevent the car from falling again and increase the safety of personnel when escaping.

[0040] In the aforementioned locking device 3, the pin 31 passes through the pin holder 32. In this way, the pin 31 is enclosed by the pin holder 32, and the pin holder 32 can provide greater resistance to deformation when the pin 31 is inserted into the socket.

[0041] The locking device 3 also includes a spring mounting plate 33 disposed on the pin 31 and a return spring 34 connecting the spring mounting plate 33 and the pin seat 32. When the elevator is in normal use, the trigger block 51 is placed back in the machine room, and the return spring 34 can ensure that the pin 31 is in the disengaged state, thus not affecting the normal use of the elevator.

[0042] It also includes a release device 6; the release device 6 includes a drum 61 located in the machine room, a connecting rope 62 wound around the drum 61 and connected to the trigger block, and a guide wheel 63 located in the machine room. The connecting rope 62 is wound around the guide wheel 63. The drum 61 and the guide wheel 63 can be specifically mounted on the mounting bracket 01 via a bracket. The release device 6 serves two purposes: firstly, the drum 61 allows the trigger block 51 to move slowly downwards and smoothly press against the inclined plane 211, preventing a violent impact that could cause greater panic; secondly, after the rescue is completed, the drum 61 can be used directly in the machine room to return the trigger block 51 to the machine room, making the operation simple and convenient.

[0043] In this embodiment, preferably, there are two moving blocks 2 and locking devices 3, which are symmetrically arranged on the top of the car 1, and each moving block 2 is provided with a corresponding triggering mechanism 5.

[0044] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. All technical contents for which protection is sought in this invention have been fully described in the claims.
