DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0041] Figure 1 A structural schematic diagram of a steel platform disclosed in the embodiments of the present application is shown, which is installed inside an elevator shaft 6. After the steel platform is put into the elevator shaft 6, the size of the motor shaft can be self-adapted by the set telescopic climber 3, and the steel platform can be moved in the elevator shaft 6 without using hoisting tools during the movement of the steel platform. Compared with the existing elevator shaft 6 construction platform, a large amount of communication time can be saved, and the efficiency of the construction in the elevator shaft 6 can be effectively improved.

[0042] Figures 2-5 A structural schematic diagram of a steel platform disclosed in the embodiments of the present application is shown, which includes a base 1. An installation table is arranged below the base 1. At least one installation surface is arranged on each side of the installation table. At least two installation grooves are arranged on the installation surface. A telescopic climber 3 is installed in the installation groove. The telescopic climber 3 can be extended out of the installation groove or retracted into the installation groove. A lifting platform 4 is installed above the base 1. A hydraulic telescopic clamping plate 51 is installed on the side of the base 1 facing the elevator door. A jacking device 52 is installed on the side of the base 1 away from the elevator door. The hydraulic telescopic clamping plate 51 and the at least two jacking devices 52 constitute a fixing mechanism 5.

[0043] The fixing mechanism 5 is used in the process. After the steel platform is moved to the door hole of the elevator door, the hydraulic telescopic clamping plate 51 is extended above the floor 7, and the jacking device 52 is extended to abut against the inner wall of the elevator shaft 6. A fixed structure is formed by using the support of the floor 7 and the inner wall of the elevator shaft 6. The steel platform is fixed at each layer of the elevator shaft 6 to facilitate construction.

[0044] As shown in the drawings, Figures 1-3 The hydraulic telescopic clamping plate 51 includes a hydraulic telescopic device 511 and a telescopic plate 512. The hydraulic telescopic device 511 is installed on the side of the base 1 facing the elevator door. The telescopic plate 512 is installed together with the output end of the hydraulic telescopic device 511. The signal output end of the controller 8 is in communication connection with the signal input end of the hydraulic telescopic device 511. The jacking device 52 includes a jacking hydraulic cylinder 521 and a support head 522. The jacking hydraulic cylinder 521 is installed on the side of the base 1 away from the elevator door. The support head 522 is connected together with the output shaft of the jacking hydraulic cylinder 521. The signal output end of the controller 8 is in communication connection with the signal input end of the jacking hydraulic cylinder 521.

[0045] The hydraulic telescopic device 511 is a prior art, which comprises at least one hydraulic cylinder and an external shell. By controlling the extension and retraction of the hydraulic cylinder, the telescopic plate 512 is pushed out of or retracted into the shell, so as to fix or release the position of the steel platform. The hydraulic cylinder in the hydraulic telescopic device 511 is in communication connection with the controller 8, and the working state thereof is controlled by the controller 8.

[0046] In the non-climbing state, the controller 8 controls the hydraulic telescopic device 511 to drive the telescopic plate 512 to extend out. After the telescopic plate 512 extends out and passes through the door hole of the elevator door of the elevator shaft 6, the telescopic plate 512 extends above the floor 7. At the same time, the controller 8 controls the extension of the hydraulic cylinder 521 to drive the support head 522 to abut against the inner wall of the elevator shaft 6. At this time, the fixing of the position of the steel platform is completed.

[0047] In the climbing state, the controller 8 controls the hydraulic telescopic device 511 to drive the telescopic plate 512 to retract. After the telescopic plate 512 is separated from the floor 7, the telescopic plate 512 retracts to the original position. At this time, the telescopic plate 512 does not contact the inner wall of the elevator shaft 6 during the movement of the steel platform. At the same time, the controller 8 controls the retraction of the hydraulic cylinder 521 to drive the support head 522 to separate from the inner wall of the elevator shaft 6 and retract to the original position. At this time, the support head 522 does not contact the inner wall of the elevator shaft 6 during the movement of the steel platform. At this time, the fixing state of the steel platform is released.

[0048] As shown in Figures 2-11 The telescopic climbing device 3 comprises a hydraulic pusher 31 and a climbing mechanism 32. The hydraulic pusher 31 comprises a guide rail 311 installed in the installation groove. The guide rail 311 is internally provided with a push hydraulic cylinder 312. The guide rail 311 is provided with a push rod 313 in sliding connection therewith. The output shaft of the push hydraulic cylinder 312 is connected with one end of the push rod 313. The other end of the push rod 313 is connected with the climbing mechanism 32.

[0049] The climbing mechanism 32 comprises a fixing frame 321 connected with the other end of the push rod 313, the fixing frame 321 is internally provided with a transmission area 321a and a mounting area 321b, the fixing frame 321 is provided with a driving motor 323 on the side close to the push rod 313, a driving shaft 324 is rotatably arranged in the transmission area 321a, at least one first reversing bevel gear set 326 is fixedly arranged on the driving shaft 324, at least one pair of wheels 322 is rotatably arranged in the mounting area 321b, a second reversing bevel gear set 327 is arranged on the shaft connecting the two wheels 322, the output end of the first reversing bevel gear set 326 and the input end of the second reversing bevel gear set 327 are connected together through a connecting shaft 328, so as to transmit the power of the first reversing bevel gear set 326 to the second reversing bevel gear set 327 to drive the wheels 322 to move, the output shaft of the driving motor 323 is connected with the first bevel gear 325 of the transmission area 321a, and the first bevel gear 325 is engaged with the input end of the first reversing bevel gear set 326.

[0050] As shown in Figure 12 The signal output end of the controller 8 is in signal input communication connection with the push hydraulic cylinder 312 and the driving motor 323 respectively.

[0051] The controller 8 is also used to acquire oil pressure data of the push hydraulic cylinder 312, and judge the stability of the steel platform according to the oil pressure data.

[0052] In the climbing state: the controller 8 drives the push hydraulic cylinder 312 to extend, and pushes out the climbing mechanism 32 through the push rod 313, at this time the controller 8 judges the current load resisting the well wall according to the oil pressure data, calculates the friction and the vertical load that can be borne, and calculates whether it is greater than the vertical load of the steel platform (the weight of the steel platform and the weight above the lifting platform 4, wherein the weight above the lifting platform 4 can be acquired by using a pressure sensor or calculated according to the set maximum bearing weight, that is, a maximum weight is preset as the weight above the lifting platform 4), according to the set threshold value, when the vertical load that can be borne is greater than the vertical load of the steel platform, and the difference is higher than the set threshold value, it is judged to be stable at this time, otherwise it is judged to be unstable, when it is judged to be stable, the fixing state of the fixing mechanism 5 is released (the fixing mechanism 5 is closed), the controller 8 controls the driving motor 323 of the climbing mechanism 32, drives the wheels 322 to rotate through the driving shaft 324, the first bevel gear 325, the first reversing bevel gear set 326, the second reversing bevel gear set 327 and the connecting shaft 328, and realizes the lifting or lowering of the position of the steel platform.

[0053] The first reversing bevel gear set 326 and the second reversing bevel gear set 327 are both composed of two mutually perpendicular bevel gears engaged, for changing the transmission direction of the power, realizing the purpose of driving the wheels 322 to run.

[0054] In non-climbing state: When reaching the doorway of the next elevator door, open the fixing mechanism 5 and close the telescopic climber 3.

[0055] The aforementioned hydraulic pushers 31 can extend or retract independently, meaning they can freely extend or retract to different lengths to adapt to working in different elevator shafts 6.

[0056] like Figures 2-12 As shown, the lifting platform 4 includes a forklift type lift 42, which is installed on the top of the base 1, and an operating platform 41 is installed on the top of the forklift type lift 42.

[0057] The existing technology used in the above-mentioned forklift lift 42 includes hydraulic rods and forklift frames. The specific working principle will not be described in detail here. The hydraulic rods are connected to the controller 8 for communication. The controller 8 controls the working state of the hydraulic rods to realize the forklift lift 42 pushing the operating platform 41 to rise or fall.

[0058] In one embodiment, at least one distance sensor 43 is provided on each side of the control panel 41, the signal output terminal of the controller 8 is communicatively connected to the signal input terminal of the forklift 42, and the signal input terminal of the controller is communicatively connected to the signal output terminal of the distance sensor 43.

[0059] During the climbing or lifting process, the controller 8 can determine whether there is a risk of collision with the wall of the elevator shaft 6 based on the signal detected by the distance sensor 43. When a danger is detected, the controller will automatically stop the operation to improve safety.

[0060] In another embodiment, the top edge of the control panel 41 is hinged with a split folding pedal 44, which includes pedal a441 and pedal b442, and pedal a441 and pedal b442 can be folded or opened independently.

[0061] It facilitates work, such as the split-type folding pedal 44 which overlaps with the work area, allowing only the part to be folded open to avoid obstructing the work area, thus improving work convenience.

[0062] After the steel platform is placed into the elevator shaft 6, the telescopic climber 3 can adapt to the size of the motor shaft. During the movement of the steel platform, it can be moved within the elevator shaft 6 without the use of hoisting tools. Compared with the existing elevator shaft 6 construction platform, it saves a lot of communication time and improves the efficiency of construction within the elevator shaft 6.

[0063] This steel platform has a lifting platform 4, which can be adjusted in height according to the construction progress. Compared with the existing elevator shaft 6 construction platform, it can complete construction at different heights without the need for climbing tools, which can save a lot of time and effectively improve construction efficiency.

[0064] It should be noted that the pushing hydraulic cylinder 312, the driving motor 323, the hydraulic telescopic device 511, the pushing and stretching hydraulic cylinder 521, the fork arm lifter 42, the distance sensor 43, and the controller 8 are selected according to the actual specifications of the device, and the specific selection calculation method is based on the existing technology in the field, so it is not described in detail.

[0065] The power supply and principle of the pushing hydraulic cylinder 312, the driving motor 323, the hydraulic telescopic device 511, the pushing and stretching hydraulic cylinder 521, the fork arm lifter 42, the distance sensor 43, and the controller 8 are clear to those skilled in the art, and are not described in detail here.

[0066] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
