Description

Technical Field

[0001] The invention relates to the technical field of brackets, in particular to an elevator direction guiding counterweight guide rail frame. Background Art

[0002] In the elevator system, the counterweight guide rail plays a vital role. It not only provides stable guidance for the counterweight to ensure the smooth operation of the elevator, but also bears the weight of the counterweight and various forces during operation.

[0003] According to the Chinese patent publication number CN105253741B, the patent provides an elevator direction guiding counterweight guide rail frame, including a shaft wall, a bracket, a locking screw, a second locking screw, a guide rail frame, a waist-shaped groove, a slide groove, a guide rail, an adjusting screw, and a counterweight block. The number of the brackets is several, and the brackets are symmetrically distributed from top to bottom on the left and right sides of the front end of the shaft wall. The bracket is an L-shaped steel frame, and the number of the locking screws is two. First, the bracket is fixed to the shaft wall by the locking screw, and then the guide rail frame is fixed to the bracket by the second locking screw. The guide rail frame is mounted on the guide rail frame, and the front and rear position of the guide rail frame can be adjusted front and rear through the waist-shaped groove. The guide rail is installed into the sliding groove at the front end of the guide rail frame, and the left and right distance of the guide rail is continuously adjusted through the adjusting screws at the left and right ends of the guide rail frame, and the guide rail is locked on the guide rail frame through the adjusting screws, thereby achieving the purpose of reasonably installing the counterweight on the guide rail, so that the guide rail plays a good guiding role for the counterweight. The guide rail frame has a simple structure and powerful functions, and can realize the front and rear left and right adjustment of the guide rail, so that a variety of counterweights can be installed, thereby achieving universality, meeting market demand, and facilitating market promotion.

[0004] However, after long-term use, the guide rail frame of the counterweight will reduce its guiding accuracy due to the wear of the guide rails, installation errors and other reasons.

The head collision protection by the buffer alone has great limitations, which may lead to direct damage to the guide rail frame and the counterweight block, causing serious losses.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an elevator direction guiding counterweight guide rail frame, which has the following beneficial effects:

[0019] 1. The direction-guiding counterweight guide rail frame of the elevator adopts a structure composed of components such as the crossbeam, U-shaped frame, L-shaped arm, buffer pad, spring and other components of the buffer part. When the elevator fails, the impact of the counterweight can be effectively buffered. When the counterweight frame hits the top, the L-shaped arm extending from the top will preferentially contact the ceiling and slide along the inner wall of the U-shaped frame by extrusion, while stretching the spring for buffering. The L-shaped arm is inserted between two gears to produce meshing, driving the gears to produce a rotational motion opposite to the previous one, so that the counterweight frame rebounds and resets a certain distance along the guide rail, avoiding the counterweight frame directly hitting the ceiling to cause scrapping and huge safety risks. When the counterweight frame falls, the L-shaped arm below will preferentially contact the ground, be inserted between the two gears to prompt the counterweight frame to rebound and reset a certain distance, and use springs and buffer pads to improve the buffering capacity. The buffer pad continues to provide shock absorption when it contacts the buffer collision head, thereby improving the protection capability under elevator failure.

[0020] 2. The direction-guiding counterweight guide rail frame of the elevator adopts two mounting frames of the guide part which are respectively installed on the front and back sides of one side of the counterweight frame. The outer wall of the guide wheel which is rotatably connected at the end is in contact with the guide rail, and the guide wheel adopts a colloid structure with anti-slip ability, which can reduce the friction between the counterweight and the guide rail, ensure the guiding accuracy of the counterweight, reduce the shaking and noise during the operation of the elevator, improve the riding comfort and the safe operation of the elevator, and the coordination part enables each guide wheel to rotate synchronously through the cooperation of the rotating shaft, pulley and transmission belt, which further improves the stability and balance of the guidance and ensures that the counterweight can run smoothly along the guide rail.

[0021] 3. The elevator direction guiding counterweight guide rail frame adopts the L-shaped arm, connecting arm, electric push rod, U-shaped arm and locking rod of the locking part. When the differential speed between the elevator car and the counterweight frame is abnormal, the abnormal signal can be sensed by the traction wheel encoder, and the inner rod of the electric push rod contracts to drive the locking rod to push out, immediately blocking the swing of the sliding arm and stopping the rotation of the gear, thereby locking the guide wheel, and generating strong friction on the guide rail through the guide wheel to prevent the counterweight frame from hitting the top or falling, further improving the safety and emergency capability of the elevator under fault conditions.

[0022] 4. The direction-guiding counterweight guide rail frame of the elevator adopts a reasonable structural design of the counterweight frame, with counterweight blocks installed inside, buffer bumpers installed at the bottom, guide shoes installed on the top and bottom sides, and a traction wheel corresponding to the elevator machine room installed on the top. The various components cooperate with each other, and the structural design of the guiding part, collaborative part, collaborative assembly, buffer part and locking part is reasonable and closely coordinated with each other, forming a complete counterweight device together, which can run stably along the guide rail and withstand various forces.

[0023] 5. The direction-guiding counterweight guide rail frame of the elevator adopts a relatively simple component installation method on the counterweight frame. The mounting frame of the guide part is installed on the counterweight frame, and the coordination part, coordination assembly, buffer part and locking part and other components are installed in the corresponding positions of the guide part and buffer part in sequence. The installation process conforms to the general mechanical installation process and does not require special installation tools and complicated installation processes. In terms of maintenance, since the structure of each component is relatively clear, when problems occur, maintenance personnel can easily check and replace the components. If the electric push rod of the locking part fails, it can be relatively easy to detect and repair. If the spring of the buffer part is damaged, it can also be easily replaced.

[0036] In the present invention, in order to further improve the lifting stability of the counterweight frame 1 on the guide rail, the guide part 2 of the present case includes two mounting frames 21, and the two mounting frames 21 are respectively installed on the front and back sides of one side of the counterweight frame 1. A support frame 22 is fixedly connected to the mounting frame 21 on the front side of the counterweight frame 1, and an L-shaped block 23 is fixedly connected to the front side of the mounting frame 21. The ends of the two mounting frames 21 extend to the outside of the side wall of the counterweight frame 1, and a guide wheel 24 is rotatably connected between the ends of the two mounting frames 21, and the outer wall of the guide wheel 24 fits the guide rail. , and the wheel wall of the guide wheel 24 adopts a colloid structure with a certain anti-slip ability. In order to make each guide wheel 24 rotate synchronously, the cooperation part 3 of this case includes a rotating shaft 1 31, and the rotating shaft 1 31 is rotatably connected to the middle of the mounting frame 21 on the front of the counterweight frame 1. The front of the mounting frame 21 on the front of the counterweight frame 1 is movably penetrated by a rotating shaft 2 32 at both ends. The penetration ends of the two rotating shafts 2 32 are respectively fixedly connected to the shaft ends of the two guide wheels 24. The middle part of the support frame 22 is rotatably connected to a rotating shaft 3 33. The outer wall of the L-shaped block 23 The front side is rotatably connected with a rotating shaft 4 34, and the rotating shaft 1 31, the rotating shaft 33 and the two rotating shafts 2 32 are all fixedly sleeved with pulleys 35, and a transmission belt is connected between the four pulleys 35. The pulley 35 on the rotating shaft 33 increases the tension of the transmission belt to ensure the friction of the transmission. In order to actively control the rotation state of the guide wheel 24 for timely protection in the event of an elevator failure, the collaborative component 4 in this case includes a sliding sleeve 41, the end of the sliding sleeve 41 is fixedly sleeved on the rotating shaft 4 34, and the inner wall of the sliding sleeve 41 is slidably connected with a sliding sleeve 41. Arm 42, a gear 43 is fixedly sleeved on the rotating shaft 31, the front side of the gear 43 is rotatably connected to the rotating shaft 5 44 and is eccentrically arranged, the end of the sliding arm 42 is fixedly sleeved on the rotating shaft 5 44, the number of the guide part 2, the cooperative part 3 and the cooperative component 4 are two each, and the other guide part 2, the cooperative part 3 and the cooperative component 4 are all installed on the front and back sides of the other side of the counterweight frame 1, the two guide parts 2, the cooperative parts 3 and the cooperative components 4 are symmetrically arranged with each other, and the symmetrical arrangement ensures the force balance of the counterweight frame 1 during the guiding period and emergency protection.

[0037] In this embodiment, in order to reduce the damage caused by the falling and hitting of the counterweight frame 1 when the elevator fails, the buffer part 5 of this case includes a crossbeam 51, which is fixedly connected between the two mounting frames 21 on the front of the counterweight frame 1, and a U-shaped frame 52 is fixedly connected to the front of the crossbeam 51. An L-shaped arm 53 is slidably connected between the inner wall of the U-shaped frame 52 and the crossbeam 51, and a buffer pad 54 is fixedly connected to the bottom of one end of the L-shaped arm 53. Connecting blocks 1 55 are fixedly connected to both sides of the U-shaped frame 52, and connecting blocks 2 56 are fixedly connected to both sides of the L-shaped arm 53. A spring 57 is elastically connected between each connecting block 1 55 and the corresponding connecting block 2 56. Meshing teeth corresponding to the gear 43 are arranged on both sides of the end of the L-shaped arm 53 away from the buffer pad 54. There are two buffer parts 5, and the two buffer parts 5 are installed between the two mounting frames 21 on the front of the counterweight frame 1, and are symmetrically arranged with the middle part of the two mounting frames 21 as the axis.

[0038] It is worth noting that in order to lock the counterweight frame 1 in time when the differential speed between the elevator car and the counterweight frame 1 is abnormal, the locking part 6 in this case is installed on the buffer part 5 located below the mounting frame 21. The locking part 6 includes two L-shaped arms 61, and the two L-shaped arms 61 are symmetrically installed on the front side of the crossbeam 51. A connecting arm 62 is integrally connected between the top ends of the two L-shaped arms 61. Electric push rods 63 are installed at the inner angles of the two L-shaped arms 61. The inner rods of the two electric push rods 63 slide through the L-shaped arms 61 respectively. The inner rod ends of the two electric push rods 63 are fixedly connected with U-shaped arms 64. The back bends of the U-shaped arms 64 are fixedly connected with locking rods 65. The two locking rods 65 slide through the ends of the two L-shaped arms 61 respectively. The front sides of the two sliding arms 42 in the two cooperative components 4 are respectively in contact with the back sides of the two L-shaped arms 61, and the front side of the L-shaped arm 53 below the mounting frame 21 is in contact with the back side of the connecting arm 62.

[0039] It is worth noting that in order to improve the automated emergency protection capability under elevator failure, a counterweight block 7 is installed inside the counterweight frame 1 in this case, a buffer head 8 is installed at the bottom of the counterweight frame 1, and guide shoes 9 are installed on both sides of the top and bottom of the counterweight frame 1. The guide shoes 9 move up and down along the guide rails. The guide rails on both sides are between the side walls of the counterweight frame 1 and the corresponding guide wheels 24. In this case, each side of the guide rail adopts a double-track structure. The tracks close to each other on both sides are respectively connected to the guide shoes 9 on both sides, and the tracks far away from each other and close to the elevator shaft on both sides are in contact with the guide wheels 24. A traction wheel corresponding to the elevator machine room is installed on the top of the counterweight frame 1, and two electric push rods 63 are electrically connected to the traction wheel encoder in the elevator machine room. The traction wheel encoder consists of a coding disk and a photoelectric detection The encoder is a disc with evenly distributed light-transmitting and opaque areas, which rotates synchronously with the shaft. The photoelectric detection device includes a light-emitting diode and a photodiode, which are located on both sides of the encoder. When the elevator motor drives the shaft to rotate, the encoder also rotates. The light-emitting diode in the photoelectric detection device emits light, which shines on the photodiode through the light-transmitting area on the encoder, generating an electrical signal. When the opaque area of ​​the encoder passes through, the light is blocked, the photodiode cannot receive the light, and the electrical signal changes, thus generating a series of pulse signals. The frequency of the pulse signal is proportional to the rotation speed of the encoder, and the rotation speed of the encoder has a certain transmission ratio relationship with the lifting speed of the elevator. By counting and processing the pulse signal, combined with the known transmission ratio, the lifting speed of the elevator can be calculated.

[0040] Working principle: the counterweight frame 1, the counterweight block 7, the buffer head 8, the guide shoe 9 and the traction wheel on the counterweight frame 1 together constitute a complete counterweight device, which is raised and lowered along the guide rail through ropes to reduce the lifting weight of the traction machine in the machine room and to promote relative balance between the counterweight device and the elevator car during operation.

[0041] The guide rail adopts a double-track structure, that is, there are two tracks on each side of the counterweight device, and it is raised and lowered on the inner track through the guide shoe 9. The inner track is located between the guide wheel 24 and the counterweight device, and the guide wheel 24 is fitted to the outer track, that is, the guide wheel 24 is located between the two tracks on the same side and does not fit the inner track. Therefore, the lifting stability is further improved by the double limiting effect of the guide shoe 9 and the guide wheel 24. The colloid material of the guide wheel 24 ensures the guiding accuracy of the counterweight, reduces the shaking and noise during the operation of the elevator, improves the riding comfort and the safe operation of the elevator, and the guide wheel 24 is raised and lowered along the guide rail and rotates, thereby synchronously driving each pulley 35 to rotate through the transmission belt, so that the rotation speed of each guide wheel 24 is the same, further improving the stability and balance of the guidance.

[0042] During the rotation of the guide wheel 24, the pulley 35 rotates to cause the gear 43 on the rotating shaft 31 to rotate synchronously, thereby synchronously driving the sliding arm 42 to slide along the inner wall of the sliding sleeve 41 and swing eccentrically around the gear 43. When the elevator fails, the traditional counterweight frame 1 will have the risk of hitting the top and falling due to the increase in the differential speed between the elevator car and itself. In this case, when the encoder of the traction wheel in the machine room senses the abnormal differential speed, it will respond to the electric signal to open the electric push rod 63, causing the inner rod of the electric push rod 63 to contract, and synchronously drive the U-shaped support arm 6 4 approaches the connecting arm 62, thereby pushing out the locking rod 65, which immediately blocks the swing of the sliding arm 42 and stops the rotation of the gear 43, thereby limiting the pulley 35 and the transmission belt from continuing to work, thereby locking the guide wheel 24, and the guide wheel 24 stops rotating in time and generates a strong friction force on the guide rail. At this time, the guide wheel 24 provides emergency protection for the counterweight frame 1 in this case, thereby preventing the differential from continuing to increase, and even directly stopping the counterweight frame 1 from hitting the top or falling, further improving the safety and emergency response capabilities under elevator failures.

[0043] When the counterweight frame 1 is still in the process of hitting the top or falling, the L-shaped arm 53 extending from the top of the counterweight frame 1 will first contact the ceiling and slide along the inner wall of the U-shaped frame 52 by squeezing, while the tension spring 57 is used for buffering. At this time, the L-shaped arm 53 will be inserted between the two gears 43 to produce meshing, and drive the gear 43 to produce a rotational movement opposite to the previous one. Even when the locking rod 65 is locked, there is still a certain rotation angle for the gear 43 to rotate and then lock. When the gear 43 drives the guide wheel 24 to rotate a certain angle, The friction force can be used to rebound the counterweight frame 1 along the guide rail to a certain distance, thereby preventing the counterweight frame 1 from directly hitting the ceiling and causing scrapping and huge safety risks. At the same time, as the depth of the L-shaped arm 53 inserted into the gears 43 increases, the L-shaped arm 53 can be pushed against the other L-shaped arm 53, and the buffering capacity can be further improved through the spring 57 on the other L-shaped arm 53. The buffer pad 54 will also perform buffering and shock absorption after contacting the traction wheel bracket above the counterweight frame 1, further improving the automatic emergency protection guarantee capability of the counterweight frame 1 under elevator failure.

[0044] Similarly, when the counterweight frame 1 falls, the L-shaped arm 53 below will contact the ground first, and the L-shaped arm 53 inserted between the two gears 43 will cause the counterweight frame 1 to rebound and reset a certain distance, and use the spring 57 and the buffer pad 54 to improve the buffering capacity. The buffer pad 54 continues to provide shock absorption when it contacts the buffer impact head 8, thereby improving the protection capability under elevator failure.
