Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, and fig. 7, the present invention discloses a hoistway self-climbing operation platform, which includes a tower body system, a wall-attached system, and a lifting platform system 4. The lifting platform system 4 exists by attaching to the tower body system, the lifting platform system 4 is added on the tower body system, and constructors can work on the lifting platform system 4.
The wall attachment system in this solution includes two attachment mechanisms 5 vertically fixed to adjacent sides of the hoistway 3. The tower body system comprises a top working mechanism 1, a tower body 2 and a bottom driving mechanism 8 which are sequentially and fixedly connected from top to bottom. The tower body 2 is connected with the two attached mechanisms 5 in a vertical sliding mode, and the bottom driving mechanism drives the standard section of the tower body 2 to slide vertically along the two attached mechanisms 5.
The attachment mechanism 5 includes a pre-buried connector 51, a transfer base 52, a rail bracket 53, and a rack. A plurality of embedded connectors 51 are embedded along the vertical direction of the hoistway 3, and the conversion base 52 is connected to the embedded connectors 51 by bolts. The rail bracket 53 is vertically disposed, and the rail bracket 53 is fixedly installed on the switching base 52. The rack is mounted on the rail bracket 53. The rail frame 53 has several sections, and is detachably connected to the switching base 52. Correspondingly, a falling protection device 54 is also arranged at the bottom of the rail frame 53. The anti-falling device 54 is used as a protection to prevent the tower body 2 from falling down along the guide rail bracket 53 when the tower body is out of control, so as to avoid safety accidents.
The tower body 2 is formed by stacking a plurality of standard sections up and down in sequence, and the change of the whole height of the tower body 2 is realized by increasing or reducing the number of the standard sections. The standard knot is provided with a corresponding guide wheel 21, and the guide wheel 21 is connected and matched with the guide rail frame 53 in a rolling manner, so that the tower body 2 is connected with the guide rail frame 53 in a vertical sliding manner. In the present case, a hydraulic support 71 is arranged on one side of the tower body 2 away from the guide wheel 21, and a support 72 is ball-hinged at the end of the hydraulic support 71 away from the tower body 2. It should be noted that: the hydraulic support 71 may be a hydraulic cylinder, and a piston rod of the hydraulic cylinder is in a ball joint with the support 72. When the tower body 2 needs to be fixed at a certain horizontal position of the well 3, the piston rod of the hydraulic cylinder extends towards the direction away from the guide wheel 21 until the support 72 contacts with the side wall of the well 3 and presses the well 3. As shown in fig. 1, the tower 2 is supported simultaneously by the hydraulic support 71 and the two attachment mechanisms 5 to avoid the tower 2 from tilting.
The bottom driving mechanism 8 comprises a frame fixedly connected with the tower body 2, a driving machine arranged on the frame and a gear arranged on the driving machine, wherein the gear is meshed with the rack, and the driving machine drives the gear to rotate in the forward direction or the reverse direction. The driving machine can be a hydraulic driving gear pump or can be realized by directly adopting a motor matched with a speed reducer.
And a lifting platform system 4 is arranged on the tower body 2. The elevating platform system 4 is completely independent, but the elevating platform system 4 needs to exist attached to the tower body 2. The lifting platform system 4 comprises a hanging lug fixedly mounted on the tower body 2, a pulley rotatably connected with the hanging lug, a steel wire rope 41 passing around the pulley and matched with the pulley, a hanging platform 43 fixedly connected with one end of the steel wire rope 41 and a winch 42 fixedly mounted on the hanging platform 43 and connected with the other end of the steel wire rope 41, wherein the steel wire rope 41 is tightened or released by operating the winch 42 so as to lift the hanging platform 43 vertically. The hanging platform 43 may be used as a construction platform. For this reason, further optimization of the suspended platform 43 is necessary.
The top working mechanism 1 comprises a concrete spreader and a concrete pump pipe installed on the concrete spreader, and the concrete spreader is installed on the top of the tower body 2 through a converter base 11. The top working mechanism 1 is supported by the tower body 2, the top working mechanism 1 is not necessarily a concrete pump pipe, and may be a hoisting mechanism, such as a crane of a tower crane, and can be randomly arranged on the tower body 2 according to different construction occasions and use functions.
As shown in fig. 5, a reversible guard 62 is rotatably connected to the tower 2, and the edge of the reversible guard 62 away from the tower 2 is connected to the tower 2 through a lifting rope 61. The reversible protection 62 adopts a three-section type structure which is sequentially hinged and connected in the scheme, is formed by sequentially hinging three connecting plates, and simultaneously utilizes the lifting rope 61 to perform edge tying and fixing. The reversible protection 62 is mounted on top of the tower 2 in a reversible configuration for horizontal protection of the working layer hoistway 3. However, the convertible guard 62 may also be constructed as a construction platform, similar to the suspended platform 43.
An auxiliary lifting appliance and a ladder stand are arranged on the tower body 2, and a protective cage is further arranged on the ladder stand. The auxiliary hoist is typically mounted on top of the tower 2 for assisting in hoisting the working material within the hoistway 3 and for hoisting components of the wall attachment system. The following is a specific example of how the operation platform in the present case can climb in the hoistway 3:
as shown in fig. 8: in the first state, the tower 2 is fixed to the hoistway 3 by a wall attachment system.
As shown in fig. 9, the tower 2 is now raised by the bottom drive. The bottom drive mechanism drives the tower 2 to rise to a certain position along the rail frame 53 through the gears. Then, the rail brackets 53 at the lower part of the tower body 2 are removed, and the removed rail brackets 53 are mounted above the tower body 2. The rail frame 53 is still connected to the embedded connector 51 through the transfer base 52. The bottom drive mechanism is then activated again and the tower 2 continues to be driven by the bottom drive mechanism up the rail brackets 53 to the position shown in figure 10.
By repeating the above process, the tower body 2 can climb to the required height along the hoistway 3 in the above process. And the lifting platform system 4 is lifted integrally according to the height of the tower body 2. This well 3 is from climbing operation platform, and when top operating device 1 stopped the operation, construction operation personnel can attach the ann of wall system and tear open the operation on the cat ladder on the body of the tower system, and well 3 inboard template is set up and is demolishd the operation such as, also can carry out other construction operations in well 3 inboard on lift platform system 4, and is very convenient and practical.
The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
