The method of erecting a floor-type scaffold in the elevator shaft has high labor cost, long scaffold rental time, and great difficulty in safe operation of workers. If a standardized elevator shaft steel operation platform is used for safety protection, due to the heavy material, manual disassembly, transportation and erection are required on each floor, which is laborious and time-consuming during construction.

[0007] By adopting the technical scheme, the crane is connected with the lifting ring first, then the triangular support is lifted to the elevator door opening, then the upper reinforcing assembly and the lower reinforcing assembly are inserted into the elevator door opening through the driving assembly, so that the upper reinforcing assembly abuts against the upper end wall of the elevator door opening and the lower reinforcing assembly abuts against the lower end wall of the elevator door opening, and after the abutting of the upper reinforcing assembly and the lower reinforcing assembly, the position of the entire operation platform is limited at the position opposite to the elevator door opening, and at this time, the operator can operate on the operation platform; after the operation is completed, the upper reinforcing assembly and the lower reinforcing assembly are loosened and no longer abut against each other, and then the crane lifts the operation platform to the next elevator door opening; and the triangular support base under the support top plate is triangular, and the entire structure is very stable, which can improve the safety of the operator on the support top plate during operation; after such setting, it is no longer necessary to spend time and effort to erect a floor-type scaffold in the elevator shaft, and it is only necessary to lift the operation platform to the corresponding elevator door opening.

[0008] Optionally, the driving assembly comprises a driving column, a rotating rod and a push-pull rod; the driving column is vertically installed on the triangular support base and the inside of the driving column is hollow; the rotating rod is rotationally arranged in the driving column; the push-pull rod is horizontally and slidingly inserted into the driving column; a first rack is arranged on the push-pull rod along the length direction of the push-pull rod; a first gear is coaxially arranged on the rotating rod; and the first rack is engaged with the first gear; after the rotating rod rotates, the upper reinforcing assembly and the lower reinforcing assembly automatically abut against the end walls of the elevator door opening.

[0009] By adopting the technical scheme, the first rack on the push-pull rod is moved to drive the first gear to rotate, and then the rotating rod is rotated; after the rotating rod rotates, the upper reinforcing assembly and the lower reinforcing assembly are automatically driven to abut against the end walls of the elevator door opening, so that a more convenient operation effect can be achieved.

[0010] Optionally, a sliding rail is horizontally arranged on the driving column; the push-pull rod is slidingly inserted into the sliding rail; a push-pull handle is arranged at one end of the push-pull rod; and an anti-falling block is arranged at the end of the push-pull rod away from the push-pull handle.

[0011] By adopting the technical scheme, when the push-pull rod slides horizontally on the driving column, the sliding rail makes the push-pull rod move more stably in the horizontal direction; the push-pull handle can facilitate workers to push the push-pull rod; and the anti-falling block can prevent the push-pull rod from falling off the sliding rail during pushing.

[0012] Optionally, the upper reinforcing assembly comprises an upper sliding block and a second rack, the upper sliding block is horizontally slidably arranged at the upper end portion of the driving column, the second rack is arranged on the upper sliding block along the length direction of the upper sliding block, and the second gear coaxially arranged at the position close to the top of the rotating rod is engaged with the second rack.

[0013] By adopting the above technical scheme, when the rotating rod rotates, the rotating rod drives the second gear to rotate, and since the second gear is engaged with the second rack, the rotation of the second gear drives the second rack to move horizontally, so that the upper sliding block moves horizontally on the driving column, thereby achieving the effect that the upper sliding block is conveniently driven to move horizontally.

[0014] Optionally, the lower reinforcing assembly comprises a lower sliding block and a third rack, the lower sliding block is horizontally slidably arranged at the lower end portion of the driving column, the third rack is arranged on the lower sliding block along the length direction of the lower sliding block, and the third gear coaxially arranged at the position close to the bottom of the rotating rod is engaged with the third rack.

[0015] By adopting the above technical scheme, when the rotating rod rotates, the rotating rod drives the third gear to rotate, and since the third gear is engaged with the second rack, the rotation of the third gear drives the third rack to move horizontally, so that the lower sliding block moves horizontally on the driving column, thereby achieving the effect that the lower sliding block is conveniently driven to move horizontally.

[0016] Optionally, the upper sliding block and the lower sliding block are located on the same side of the rotating rod, the push-pull rod is located on the other side of the rotating rod away from the upper sliding block and the lower sliding block, and the distance between the upper sliding block and the lower sliding block is the same as the length direction of the elevator door opening.

[0017] By adopting the above technical scheme, the distance between the upper sliding block and the lower sliding block is the same as the length direction of the elevator door opening, so that the operation platform can be clamped at the elevator door opening, and the positions of the upper sliding block and the lower sliding block can enable the upper sliding block and the lower sliding block to move from inside to outside when the push-pull rod is pushed from outside to inside, that is, the moving directions of the push-pull rod, the upper sliding block and the lower sliding block are always opposite in the horizontal direction, thereby achieving the effect of driving cooperation.

[0018] Optionally, the driving column is further provided with a clamping assembly, and the clamping assembly is used to keep the upper reinforcing assembly and the lower reinforcing assembly in the abutting state at the current position.

[0019] By adopting the above technical scheme, the clamping assembly can fix the upper reinforcing assembly and the lower reinforcing assembly, thereby preventing the upper reinforcing assembly and the lower reinforcing assembly from suddenly loosening in the abutting state to a certain extent.

[0020] Optionally, the clamping assembly comprises a driving box, an upper clamping rod, a lower clamping rod, an extension box, a spring and an abutting block; the driving box is installed on the driving column and the length direction of the driving box is consistent with the length direction of the driving column, the inside of the driving box is hollow and both ends are open; the upper clamping rod and the lower clamping rod are both slidingly inserted in the driving box, the extension box is communicatively arranged in the middle of the driving box, and the extension box is located between the upper clamping rod and the lower clamping rod; the abutting block is slidingly inserted in the extension box, and the spring is provided with two in the driving box, one is sleeved on the upper clamping rod and the other is sleeved on the lower clamping rod, the abutting block is used for abutting the upper clamping rod on the upper reinforcing assembly and the lower clamping rod on the lower reinforcing assembly; the spring makes the upper clamping rod always have a downward moving trend and also makes the lower clamping rod always have an upward moving trend.

[0021] By adopting the above technical scheme, when the upper reinforcing assembly and the lower reinforcing assembly need to be reinforced, the abutting block is directly horizontally moved from the extension box into the driving box, at this time the abutting block will vertically push the upper clamping rod upward and the lower clamping rod downward; after the upper clamping rod is vertically moved upward, it will directly abut against the lower bottom wall of the upper sliding block, and after the lower clamping rod is vertically moved downward, it will directly abut against the upper top wall of the lower sliding block, through the abutment of the two, the upper sliding block and the lower sliding block will be tightly abutted at the current position, thereby achieving the effect that the upper sliding block and the lower sliding block are conveniently tightly abutted; after the abutting block is withdrawn from the driving box back into the extension box, under the elastic force of the spring, the upper clamping rod will be vertically pulled downward and the lower clamping rod will be vertically pulled upward, so that the upper sliding block and the lower sliding block are no longer tightly abutted, thereby achieving the effect that the abutment and release are convenient.

[0022] Optionally, one end of the upper clamping rod close to the abutting block and one end of the lower clamping rod close to the abutting block are both provided with an inclined slope, and the upper and lower ends of the abutting block are also respectively provided with a pushing slope slidingly fitted with the inclined slope.

[0023] By adopting the above technical scheme, when the abutting block is pushed from the extension box into the driving box, the pushing slope on the abutting block will abut against the inclined slope, and as the abutting block continues to horizontally move, the pushing slope will push away the inclined slopes on both sides, that is, the upper clamping rod will be vertically pushed upward and the lower clamping rod will be vertically pushed downward, thereby realizing the simultaneous pushing of the upper clamping rod and the lower clamping rod.

[0024] In a second aspect, the application provides a construction method of an elevator shaft lifting type triangular support operation platform, which adopts the following technical scheme:

[0025] Processing Steps: The operating platform is processed and cut according to the design dimensions. After the platform components are processed and inspected by the quality inspection department, they are submitted to the supervisor for acceptance. Flaw Detection Steps: After the platform is manufactured, flaw detection is performed. If the flaw detection fails, rework is required. Platform Lifting Steps: When lifting the platform, ropes must be attached to each of the four lifting points simultaneously. It is strictly forbidden to use one or two steel wire ropes through the lifting rings for lifting. During the lifting process, it is strictly forbidden for anyone to stand on the platform or for any objects to be piled up. The foreman is responsible for tracking and managing the construction process, and a dedicated safety officer must supervise the process. After the platform is lifted into place, it must be inspected and accepted by the general contractor and the supervision company. Platform Operation Steps: During the main construction, when the concrete strength of the lower part reaches 75% of its designed strength, the platform can be slowly lifted into the elevator shaft using a tower crane. The triangular support base frame is aligned with one side of the elevator shaft door. The upper and lower reinforcement components are used to secure the triangular support base frame to the lower edge of the elevator door opening, ultimately allowing the operating platform to rest against the shear wall. Operating precautions: When hoisting and dismantling the formwork, strictly control the hoisting speed to avoid strong impacts with the platform; a dedicated safety officer must inspect the platform daily, and if any abnormalities such as slippage of the triangular supports or weld cracks are found, effective measures must be taken immediately to completely eliminate them.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. First, connect the crane to the lifting ring, then hoist the triangular support to the elevator doorway. Next, use the drive assembly to insert the upper and lower reinforcement components into the elevator doorway, so that the upper reinforcement component abuts against the upper wall of the elevator doorway and the lower reinforcement component abuts against the lower wall of the elevator doorway. After the upper and lower reinforcement components abut against each other, the position of the entire operating platform will be fixed at the position directly opposite the elevator doorway, allowing the operator to work on the platform. After the operation is completed, release the upper and lower reinforcement components and let the crane lift the operating platform to the next elevator doorway. Moreover, the triangular support base under the supporting top plate is triangular in shape, and the entire structure is very stable, which can improve the safety of the operator on the supporting top plate during operation. With this setup, there is no need to spend time and effort to erect ground-based scaffolding in the elevator shaft; it is only necessary to hoist the operating platform to the corresponding elevator doorway.

[0028] 2. The distance between the upper and lower sliders is in the same direction as the length of the elevator doorway, so that the operating platform can be locked in the elevator doorway. The position of the upper and lower sliders allows the upper and lower sliders to move from the inside to the outside when the push rod is pushed from the outside to the inside. That is, the movement direction of the push rod and the upper and lower sliders are always opposite in the horizontal direction, thus achieving a driving coordination effect.

[0029] 3. When the upper reinforcing assembly and the lower reinforcing assembly need to be reinforced, the abutting block is directly horizontally moved from the extension box into the driving box, at this time, the abutting block will push the upper clamping rod vertically upward and the lower clamping rod vertically downward, and after the upper clamping rod is vertically moved upward, it will directly abut against the lower bottom wall of the upper sliding block, and after the lower clamping rod is vertically moved downward, it will directly abut against the upper top wall of the lower sliding block, through the abutment of the two, the upper sliding block and the lower sliding block will be tightly abutted at the current position, so that the effect of conveniently abutting the upper sliding block and the lower sliding block is achieved, and after the abutting block is retreated from the driving box into the extension box, under the elastic force of the spring, the upper clamping rod will be pulled vertically downward and the lower clamping rod will be pulled vertically upward, so that the upper sliding block and the lower sliding block are no longer tightly abutted, and the effects of conveniently abutting and loosening are achieved.

[0039] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0040] This application discloses an elevator shaft lifting triangular support operating platform. (Refer to...) Figure 1 , 2 The elevator shaft lifting triangular support operating platform includes a supporting top plate 1 and a triangular support base 2. The supporting top plate 1 is rectangular in shape. The triangular support base 2 is welded from two triangular frames arranged in parallel. One side of the triangular support base 2 is pressed against the inner wall of the elevator shaft. Four lifting rings 21 are arranged in an array on the upper surface of the supporting top plate 1. The lifting rings 21 are used for fastening when the crane lifts the elevator. A lower reinforcing component 3 is provided at the end of the triangular support base 2 away from the supporting top plate 1, and an upper reinforcing component 4 is provided at the end of the triangular support base 2 closer to the supporting top plate 1. A driving component 5 is provided between the upper reinforcing component 4 and the lower reinforcing component 3 on the triangular support base 2. The driving component 5 is used to simultaneously drive the upper reinforcing component 4 and the lower reinforcing component 3 to abut and release the upper and lower walls of the elevator door opening.

[0041] It is worth noting that the distance between the upper reinforcing component 4 and the lower reinforcing component 3 is adapted to the height of the elevator door opening. That is, by driving the upper reinforcing component 5 to move the upper reinforcing component 4 and the lower reinforcing component 3 at the same time, the upper reinforcing component 4 and the lower reinforcing component 3 will simultaneously abut against the upper and lower walls of the elevator door opening. However, when using a crane to lift and move the operating platform, care should be taken to ensure that the operating platform is aligned with the elevator door opening. This allows the upper reinforcing component 4 and the lower reinforcing component 3 to be moved horizontally from the elevator shaft into the elevator door opening to achieve a tight fit and engagement. With this setting, it is no longer necessary to spend time and effort to erect a ground-based scaffold in the elevator shaft. It is only necessary to hoist the operating platform to the corresponding elevator door opening.

[0042] like Figure 1 , 2As shown, the driving assembly 5 comprises a driving column 51, a rotating rod 52 and a push-pull rod 53; the driving column 51 is vertically installed on the triangular supporting base 2 and hollowed in the inside of the driving column 51, the rotating rod 52 is rotationally arranged in the driving column 51, the push-pull rod 53 is horizontally slidably inserted in the driving column 51, the first gear rack 531 is arranged on the push-pull rod 53 along the length direction of the push-pull rod 53, the first gear 521 is coaxially arranged on the rotating rod 52, and the first gear rack 531 is engaged with the first gear 521; after the rotating rod 52 rotates, the upper reinforcing assembly 4 and the lower reinforcing assembly 3 automatically abut.

[0043] Specifically, as shown in Figure 2 、 3 , the sliding rail 6 is horizontally arranged on the driving column 51, the push-pull rod 53 is slidably inserted in the sliding rail 6, the push-pull rod 53 is provided with a push-pull handle 532 at one end, and the push-pull rod 53 is provided with an anti-falling block 533 at the end away from the push-pull handle 532; the sliding rail 6 is hollow in the inside, open at both ends and one side, and the upper and lower inner walls of the sliding rail 6 are provided with guide strips along the length direction of the sliding rail 6, and the upper and lower rod walls of the push-pull rod 53 are provided with guide strip grooves along the length direction of the push-pull rod 53.

[0044] When the push-pull rod 53 horizontally slides on the driving column 51, the sliding rail 6 arranged can make the push-pull rod 53 move more stably in the horizontal direction; the push-pull handle 532 arranged can facilitate workers to push the push-pull rod 53; and the anti-falling block 533 arranged can prevent the push-pull rod 53 from falling off the sliding rail 6 during pushing.

[0045] In combination Figure 4 、 5 , the upper reinforcing assembly 4 comprises an upper sliding block 41 and a second gear rack 42, the upper sliding block 41 is horizontally slidably inserted in the upper end portion of the driving column 51; the second gear rack 42 is arranged on the upper sliding block 41 along the length direction of the upper sliding block 41; the second gear 522 is coaxially arranged on the rotating rod 52 close to the top, and the second gear 522 is engaged with the second gear rack 42. Similarly, the lower reinforcing assembly 3 comprises a lower sliding block 31 and a third gear rack 32, the lower sliding block 31 is horizontally slidably inserted in the lower end portion of the driving column 51; the third gear rack 32 is arranged on the lower sliding block 31 along the length direction of the lower sliding block 31; the third gear 523 is coaxially arranged on the rotating rod 52 close to the bottom, and the third gear 523 is engaged with the third gear rack 32.

[0046] When the rotating rod 52 rotates, the rotating rod 52 drives the second gear 522 to rotate, and since the second gear 522 is engaged with the second rack 42, the rotation of the second gear 522 drives the second rack 42 to move horizontally, so that the upper sliding block 41 moves on the driving column 51 in the horizontal direction, thereby achieving the effect that the upper sliding block 41 moves in the horizontal direction more conveniently; similarly, when the rotating rod 52 rotates, the rotating rod 52 drives the third gear 523 to rotate, and since the third gear 523 is engaged with the second rack 42, the rotation of the third gear 523 drives the third rack 32 to move horizontally, so that the lower sliding block 31 moves on the driving column 51 in the horizontal direction, thereby achieving the effect that the lower sliding block 31 moves in the horizontal direction more conveniently.

[0047] In combination Figure 2 , 3 , the upper sliding block 41 and the lower sliding block 31 are located on the same side of the rotating rod 52, and the push-pull rod 53 is located on the other side of the rotating rod 52 away from the upper sliding block 41 and the lower sliding block 31; and the distance between the upper sliding block 41 and the lower sliding block 31 is the same as the length direction of the elevator door opening. The distance between the upper sliding block 41 and the lower sliding block 31 is the same as the length direction of the elevator door opening, so that the operation platform can be clamped at the elevator door opening, and the positions of the upper sliding block 41 and the lower sliding block 31 can realize that when the push-pull rod 53 is pushed from outside to inside, the upper sliding block 41 and the lower sliding block 31 can move from inside to outside, that is, the moving directions of the push-pull rod 53, the upper sliding block 41 and the lower sliding block 31 are always opposite in the horizontal direction, thereby achieving the effect of driving cooperation.

Moreover, rubber blocks are arranged at the upper end of the upper clamping rod 72 and the lower end of the lower clamping rod 73, so as to avoid direct contact and damage; and a push-pull ring is arranged at one end of the abutting block 76 located outside the extension box 74, so as to facilitate pushing the abutting block 76.

[0049] When the upper reinforcing assembly 4 and the lower reinforcing assembly 3 need to be reinforced, the abutting block 76 is directly moved horizontally from the extension box 74 into the driving box 71, at this time the abutting block 76 will vertically push the upper clamping rod 72 upward and the lower clamping rod 73 downward; after the upper clamping rod 72 moves vertically upward, it will directly abut on the lower bottom wall of the upper sliding block 41, and after the lower clamping rod 73 moves vertically downward, it will directly abut on the upper top wall of the lower sliding block 31, through the abutment of the two, the upper sliding block 41 and the lower sliding block 31 will be tightly abutted at the current position, so as to achieve the effect that the upper sliding block 41 and the lower sliding block 31 are tightly abutted more conveniently; after the abutting block 76 is withdrawn from the driving box 71 back into the extension box 74, under the elastic force of the spring 75, the upper clamping rod 72 will be pulled vertically downward and the lower clamping rod 73 will be pulled vertically upward, so that the upper sliding block 41 and the lower sliding block 31 are no longer tightly abutted, thereby achieving the effect that the tightly abutment and the loosening are more convenient.
