Description

Technical Field

[0001] The utility model relates to the technical field of special equipment installation, in particular to special equipment installation auxiliary equipment. Background Art

[0002] Special equipment is divided into pressure-bearing special equipment and electromechanical special equipment. The pressure-bearing special equipment mainly includes boilers, pressure vessels, and pressure pipes. The electromechanical special equipment mainly includes elevators, lifting machinery, passenger ropeways, large amusement facilities, and special motor vehicles on site. Among them, elevators, as a kind of transportation equipment for vertical transportation of pedestrians or goods, have been widely used in life.

[0003] With the rapid development of my country's infrastructure, the use of elevators has gradually increased. When installing an elevator, it is necessary to carry out installation work in the elevator shaft. For example, a Chinese patent with the publication number CN217708434U discloses an elevator installation protection device, including two elevator shaft inner walls, two elevator shaft inner walls are vertically opened on the side close to each other, sliders are slidably connected in the two sliders, and the slider is fixedly connected with a support assembly connected to the steel cable. A vertical groove is opened on the side of the inner wall of the slider away from the support assembly, and a plurality of elastic blocking assemblies are equidistantly arranged in the vertical groove from top to bottom. Among them, this elevator installation protection device, by arranging sliders, sliders, vertical grooves, supports, blocking members and elastic members, can be used when the steel cable breaks when the staff is working at a height. The blocking member and the support member cooperate to block the slider and restrict it from continuing to fall freely, thereby effectively avoiding the free fall of the support assembly from a height, thereby avoiding the danger of the staff in the support assembly falling from a height, and avoiding casualties.

[0004] A common installation auxiliary protection device in the prior art is to block the slider by a blocking member to prevent the support member from directly falling freely from a height and causing the danger of the worker falling from a height. However, the blocking member blocks the slider, and the acceleration of the worker and the support member when falling is large. Under this premise, the impact force when the support member falls from a height may break the blocking member or the slider, resulting in the inability to block the support member, causing the worker in the support member to fall from a height and cause casualties.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A special equipment installation auxiliary device in the embodiment of the utility model, please refer to the attached figure Figure 1-Figure 5 As shown, it comprises two groups of elevator shaft inner walls 1, a construction car 2 is arranged between the two groups of elevator shaft inner walls 1, a protective door 3 is hinged on the outer wall of the construction car 2, a mounting groove 4 is provided in the construction car 2, two groups of mounting plates 44 are slidably connected in the mounting groove 4, the two groups of mounting plates 44 correspond to the two groups of elevator shaft inner walls 1 one by one, the opposite surfaces of the two groups of mounting plates 44 are fixedly connected with mounting tubes 5, the outer wall of each of the mounting tubes 5 is provided with two groups of through holes 51, each of the through holes 51 is slidably connected with a trapezoidal block 52, the opposite surfaces of the two adjacent groups of the trapezoidal blocks 52 are fixedly connected with a fixing plate 53, and an elastic component is provided between the fixing plate 53 and the mounting tube 5;

[0028] The installation tube 5 is provided with an extrusion assembly, which is used to extrude the trapezoidal block 52 outwards. The outer wall of the two groups of elevator shaft inner walls 1 close to the installation plate 44 is provided with multiple groups of connecting grooves 6. The multiple groups of connecting grooves 6 correspond to the multiple groups of installation tubes 5 one by one. Each of the connecting grooves 6 is provided with multiple groups of blocking members. The installation groove 4 is provided with a driving assembly, which is used to drive the installation plate 44 to move.

[0029] When the staff needs to carry out construction in the elevator shaft, they first open the protective door 3 and enter the construction car 2, and then drive the construction car 2 upward by the steel cable. When the construction car 2 is lifted to a suitable position, the steel cable stops moving, and then the staff drives the mounting plate 44 to move toward the inner wall 1 of the elevator shaft on both sides through the driving assembly. During the movement of the mounting plate 44, multiple groups of mounting pipes 5 will be driven to enter the connecting groove 6 respectively. When the mounting pipe 5 moves into the connecting groove 6, the extrusion assembly will squeeze the two groups of trapezoidal blocks 52 in the mounting pipe 5 outward. During the movement, the trapezoidal blocks 52 will gradually move toward the inner wall of the connecting groove 6 until the mounting pipe 5 moves to the inner wall of the connecting groove 6. The fixing plate 53 on its outer wall contacts the inner wall of the connecting groove 6. By such an arrangement, the position of the construction car 2 can be positioned and fixed under the action of multiple groups of fixing plates 53, which can not only prevent the construction car 2 from shaking due to the movement of workers during construction and cause safety hazards, but also if the steel cable breaks, the friction between the fixing plate 53 and the inner wall of the connecting groove 6 will reduce the falling speed of the construction car 2, thereby reducing the impact force of the falling construction car 2. Under this premise, the construction car 2 can be blocked by cooperating with the blocking member to prevent the workers in the construction car 2 from falling from a height and causing casualties.

[0030] As an implementation of the present invention, please refer to the attached drawings Figure 4 As shown, specifically, the blocking member includes a plurality of groups of movable grooves 61 provided on the inner walls on opposite sides of the connecting groove 6, and a third spring 62 is fixedly connected to the inner wall of each movable groove 61 away from the connecting groove 6, and a support block 63 is fixedly connected to one end of each third spring 62 close to the connecting groove 6, and the facing surfaces of the two adjacent groups of support blocks 63 are both inclined surfaces;

[0031] When the staff needs to change the construction position, they first move the construction car 2 upward through the steel cable. During the upward movement of the construction car 2, the installation tube 5 located in the connecting groove 6 will contact the inclined surface of the support block 63. As the installation tube 5 and the construction car 2 continue to move upward, the installation tube 5 will squeeze the support block 63 into the moving groove 61 and compress the third spring 62. When the installation tube 5 moves to separate from the support block 63, the two groups of support blocks 63 will move upward under the action of the elastic restoring force of the third spring 62 and contact each other. At this time, the support block 63 can block the construction car 2 on its top. If the construction car 2 falls, the two groups of support blocks 63 can block the construction car 2 to prevent it from falling directly and causing casualties to the staff inside.

[0032] As an implementation of the present invention, please refer to the attached drawings Figure 3As shown, specifically, the extrusion assembly includes an extrusion block 57 slidably connected in the mounting tube 5, and the outer wall of the extrusion block 57 close to the trapezoidal block 52 is fixedly connected to a plurality of groups of second springs 56, and one end of the second spring 56 away from the extrusion block 57 is fixedly connected to the inner wall of the mounting tube 5, and the extrusion block 57 is adapted to the size of the mounting tube 5;

[0033] When positioning and fixing the construction car 2, the two groups of mounting plates 44 will be driven by the driving assembly to move toward the inner walls 1 of the elevator shaft on both sides. As the mounting plates 44 move, the mounting tube 5 will enter the connecting groove 6. At this time, the extrusion block 57 will contact the inner wall of the connecting groove 6. As the mounting block continues to move, under the limiting action of the extrusion block 57, the two groups of trapezoidal blocks 52 will be squeezed toward the outside of the through hole 51 at the same time, and the extrusion block 57 will enter the inside of the mounting tube 5, so that the fixing plates 53 outside the trapezoidal blocks 52 are in contact with the inner wall of the connecting groove 6. At this time, the two groups of fixing plates 53 and the extrusion block 57 are respectively in contact with the three groups of inner walls of the connecting groove 6, so as to have a good positioning and fixing effect on the construction car 2, and avoid the situation where the construction car 2 shakes due to the workers walking during the construction process, thereby reducing the danger of the workers during construction;

[0034] When one construction is completed, the staff will recycle the mounting plate 44 through the driving assembly. When the mounting plate 44 moves to the side away from the inner wall 1 of the elevator shaft, it will drive the mounting tube 5 to move toward the outer wall of the connecting groove 6. At this time, the extrusion block 57 is still in contact with the inner wall of the connecting groove 6 under the action of the elastic force of the second spring 56, and gradually separates from the mounting tube 5. During this process, the extrusion block 57 will gradually separate from the inclined surface of the trapezoidal block 52. At this time, the trapezoidal block 52 will move into the mounting tube 5 under the action of the elastic component, and separate from the inner wall of the connecting groove 6, thereby releasing the positioning and fixation of the construction car 2, and the square plate steel cable will transport the construction car 2 downward.

[0035] As an implementation of the present invention, please refer to the attached drawings Figure 3 As shown, specifically, each of the mounting tubes 5 is fixedly connected with a telescopic rod 55, and one end of the telescopic rod 55 close to the extrusion block 57 is fixedly connected to the outer surface of the extrusion block 57;

[0036] When the extrusion block 57 moves, it will drive the telescopic rod 55 to contract back and forth. At this time, the telescopic rod 55 can limit the extrusion block 57 to prevent the extrusion block 57 from tilting when being squeezed, thereby ensuring that the extrusion block 57 can have a good extrusion and limiting effect on the trapezoidal block 52.

[0037] As an implementation of the present invention, please refer to the attached drawings Figure 2 , Figure 3As shown, specifically, the elastic component includes a first spring 54 fixedly connected to the outer wall of the fixing plate 53 close to the mounting tube 5, one end of the first spring 54 away from the fixing plate 53 is fixedly connected to the outer surface of the mounting tube 5, and the trapezoidal block 52 is adapted to the size of the through hole 51;

[0038] When the trapezoidal block 52 is squeezed, it will stretch the first spring 54. When the trapezoidal block 52 is no longer squeezed, it will move toward the inside of the mounting tube 5 under the action of the elastic restoring force of the first spring 54 itself, so as to facilitate subsequent use. Moreover, since the trapezoidal block 52 is adapted to the size of the through hole 51, the trapezoidal block 52 can be prevented from tilting when squeezed, thereby ensuring that the fixing plate 53 has a good contact effect with the inner wall of the connecting groove 6, thereby improving the fixing and positioning effect of the construction car 2.

[0039] As an implementation of the present invention, please refer to the attached drawings Figure 2 As shown, specifically, the driving assembly includes a bidirectional screw 41 rotatably connected in the mounting groove 4, both ends of the outer wall of the bidirectional screw 41 are threadedly connected with connecting blocks 42, two groups of the connecting blocks 42 are hinged with push rods 43 on both sides of the outer walls close to the mounting plate 44, and the ends of the push rods 43 away from the connecting blocks 42 of multiple groups are hinged with adjacent mounting plates 44, and the outer wall of the construction car 2 is fixedly connected with a driving motor 47, and the output shaft of the driving motor 47 is fixedly connected to one end of the bidirectional screw 41;

[0040] When the staff lifts the construction car 2 to the appropriate position by the steel cable, the driving motor 47 is turned on, and the output shaft of the driving motor 47 will drive the bidirectional screw 41 to rotate. The rotating bidirectional screw 41 can drive the two groups of connecting blocks 42 to move simultaneously through threaded transmission, and because the threads at both ends of the bidirectional screw 41 are in opposite directions, the bidirectional screw 41 will drive the two groups of connecting blocks 42 to move toward the center of the bidirectional screw 41 at the same time during the rotation process. As the two groups of connecting blocks 42 approach each other, the push rod 43 will be driven to push the two groups of mounting plates 44 to the outside of the mounting groove 4 at the same time, thereby facilitating the subsequent positioning and fixing of the construction car 2, which is convenient and quick.

[0041] As an implementation of the present invention, please refer to the attached drawings Figure 5 As shown, specifically, a slide groove 45 is provided on the inner wall at the bottom of the installation groove 4, and sliders 46 are fixedly connected to the bottoms of the two groups of connection blocks 42. The sliders 46 are slidably installed in the slide groove 45, and the sliders 46 are adapted to the slide groove 45 in size;

[0042] When the connecting block 42 moves, it will drive the slider 46 to move in the slide groove 45. Since the slider 46 is adapted to the slide groove 45 in size, the slider 46 can limit the connecting block 42, thereby avoiding the situation where the friction between the connecting block 42 and the bidirectional screw rod 41 is too large, causing the bidirectional screw rod 41 to drive the connecting block 42 to rotate or tilt synchronously during the rotation process. This ensures that the two groups of connecting blocks 42 can move at the same time when the bidirectional screw rod 41 rotates without tilting, thereby ensuring the normal movement of the two groups of mounting plates 44, which is convenient for the subsequent positioning and fixation of the construction car 2.

[0043] Working principle: When the staff needs to carry out construction in the elevator shaft, they first open the protective door 3 and enter the construction car 2, and then use the steel cable to drive the construction car 2 to lift upward. When the construction car 2 is lifted to the appropriate position, the steel cable stops moving, and then the drive motor 47 is turned on. The output shaft of the drive motor 47 will drive the two-way screw rod 41 to rotate. The rotating two-way screw rod 41 can drive the two groups of connecting blocks 42 to move simultaneously through thread transmission, and because the threads at both ends of the two-way screw rod 41 are in opposite directions, the two-way screw rod 41 will drive the two groups of connecting blocks 42 to move toward the center of the two-way screw rod 41 at the same time during the rotation process. As the two groups of connecting blocks 42 approach each other, the push rod 43 will be driven to push the two groups of mounting plates 44 to the outside of the mounting groove 4 at the same time. During the movement of the mounting plate 44, multiple groups of mounting pipes 5 will be driven to enter the connecting groove 6 respectively. When the mounting pipe 5 moves toward the inside of the connecting groove 6, the extrusion block 57 will contact the inner wall of the connecting groove 6. As the mounting block The continued movement of the extrusion block 57 will squeeze the two groups of trapezoidal blocks 52 toward the outside of the through hole 51 at the same time, and the extrusion block 57 will enter the interior of the installation tube 5, so that the fixing plate 53 outside the trapezoidal block 52 fits with the inner wall of the connecting groove 6. At this time, the two groups of fixing plates 53 and the extrusion block 57 respectively fit with the three groups of inner walls of the connecting groove 6, thereby having a good positioning and fixing effect on the construction car 2. Through such an arrangement, under the action of multiple groups of fixing plates 53, the position of the construction car 2 can be positioned and fixed, which can not only prevent the construction car 2 from shaking due to the movement of the workers during construction, but also prevent the safety hazards caused by the construction car 2. If the steel cable breaks, at this time, under the action of the friction between the fixing plate 53 and the inner wall of the connecting groove 6, the falling speed of the construction car 2 will be reduced, thereby reducing the impact force of the construction car 2 falling. Under this premise, the construction car 2 can be blocked by cooperating with the blocking member to prevent the workers in the construction car 2 from falling from a height and causing casualties.

[0044] When the staff needs to change the construction position, they first move the construction car 2 upward through the steel cable. During the upward movement of the construction car 2, the installation tube 5 located in the connecting groove 6 will contact the inclined surface of the support block 63. As the installation tube 5 and the construction car 2 continue to move upward, the installation tube 5 will squeeze the support block 63 into the moving groove 61 and compress the third spring 62. When the installation tube 5 moves to separate from the support block 63, the two groups of support blocks 63 will move upward under the action of the elastic restoring force of the third spring 62 and contact each other. At this time, the support block 63 can block the construction car 2 on its top. If the construction car 2 falls, the two groups of support blocks 63 can block the construction car 2 to prevent it from falling directly and causing casualties to the staff inside.

[0045] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
