Description

[0002] The current building project has a generally high building height, and the building unit inevitably needs to be equipped with an indoor elevator. How to do well in high-altitude protection during the structure construction of the engineering project and the later masonry construction around the elevator shaft is one of the difficulties in construction safety management.

[0003] For the safety protection problem of the elevator shaft, two ways are mainly used to solve the problem at the present stage: one is to use a finished elevator shaft operation platform, which needs to be hoisted after each construction of a layer of structure by using a tower crane. The tower crane is frequently occupied, which affects the hoisting of construction and turnover materials, and the finished elevator shaft operation platform needs to be hoisted away before the structure of the elevator shaft is capped. The operation platform still needs to be erected for the later masonry construction around the elevator shaft and other construction operations in the elevator shaft, which affects the construction progress and is not economical. The second is to directly erect an operation platform in the elevator shaft. If the building height is high and the number of floors is large, a segmented operation platform needs to be set up by using an I-steel on the corresponding floors. At the same time, the setting of the I-steel affects the later masonry construction. Overall, this scheme is not economical and affects the later construction.

DETAILED DESCRIPTION

[0033] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely.

[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figures 1-15 The present application provides a technical solution: a self-lifting adjustable elevator shaft operation platform. The present application makes corresponding improvements for the technical problems in the background art. The operation platform includes a support body 1, a patterned steel plate one 2 fixedly installed on the support body 1, and a patterned steel plate two 3 in sliding connection with the support body 1. The patterned steel plate two 3 is in contact with and in sliding connection with the upper surface of the patterned steel plate one 2. A steel I one 4 is fixedly installed at one end of the support body 1, and a steel I two 5 is arranged on one side of the steel I one 4. The patterned steel plate two 3 is fixedly connected between the side wall of the steel I two 5. Two telescopic sleeves 6 are symmetrically fixedly installed on the two sides of the support body 1, that is, two telescopic sleeves 6 are installed on one side of the support body 1, and one end of the telescopic sleeve 6 is fixedly connected with the steel I one 4. A telescopic steel pipe 7 is symmetrically fixedly installed on the steel I two 5, and the telescopic steel pipe 7 is limitingly and slidably arranged in the telescopic sleeve 6. That is, the patterned steel plate one 2 and the patterned steel plate two 3 are adjusted in position in the horizontal direction, so as to be adapted to elevator shafts of different sizes. That is, the patterned steel plate one 2 and the patterned steel plate two 3 can perform telescopic action (the movement directions of the two are opposite) to adapt to elevator shafts of different lengths. It is further stated that, generally, the width values of elevator shafts are not obviously different, and the numerical difference generally exists in the length values of elevator shafts. The patterned steel plate one 2 and the patterned steel plate two 3 in the present application are appropriately adjusted in length, and the position adjustment in the following description is the adjustment of the length value, which is further described in the present application.

[0035] When different structural layers are constructed, the operation platform (that is, including the support body 1, the patterned steel plate one 2, the patterned steel plate two 3, the steel I one 4, the steel I two 5, the telescopic sleeve 6, and the telescopic steel pipe 7 in the present application, and the same below) needs to be adjusted in position accordingly. The operation is relatively trivial. Combined with the drawings Figures 1-3: two electric hoists 14 are installed on the superstructure layer to work synchronously, and the telescopic sleeve 6 (installed on the support body 1) in the application is provided with a lifting lug 15, and the height of the operation platform is adjusted by the electric hoists 14, and further, the operation platform in the application is located in the middle region of the elevator shaft, and then when the patterned steel plate one 2 and the patterned steel plate two 3 are away from the side wall of the elevator shaft by a certain distance, the patterned steel plate one 2 and the patterned steel plate two 3 can be expanded towards the side wall of the elevator shaft through the telescopic sleeve 6 and the telescopic steel pipe 7, and compared with the prior art, the tower crane device is not needed, and the operation is relatively simple; at the same time, in order to ensure the stability of the lifting work, the application is provided with a channel steel 16 on the structure surface, the channel steel 16 serves as a track, the I-beam one 4 and the I-beam two 5 are located in the channel steel 16 and slide in the channel steel 16 to prevent the left and right displacement, further, the channel steel 16 is welded with a steel plate body 17 on the side, and the steel plate body 17 is fixed with the structure surface by bolts, and it should be noted that the channel steel 16 (including the steel plate body 17) in the application is installed on the structure surface in multiple sections, i.e. segmented, when rising to the specified position, the channel steel 16 below which is not used any more can be removed and laid (fixed by bolts) at the rising track of the operation platform, and the upper and lower parts of the operation platform are respectively provided with a anti-collision baffle 18 and an anti-falling baffle 19, and both are fixed and connected with the structure surface by bolts;

[0036] Specifically, in the initial state, the operation platform is located in the middle region of the elevator shaft, and in the actual construction process, the construction personnel adjust the positions of the patterned steel plate one 2 and the patterned steel plate two 3 according to the length value of the elevator shaft, i.e. the construction personnel respectively pull outwards (or push inwards) the I-beam one 4 and the I-beam two 5, so that the patterned steel plate one 2 and the patterned steel plate two 3 are adjusted in position under the action of the telescopic sleeve 6 and the telescopic rod frame 7, after the adjustment is completed, the workers install the channel steel 16 on the structure surface, i.e. the steel plate body 17 on one side of the channel steel 16 is in contact with the structure surface and is fixed by bolts, and then the operation platform is automatically lifted by the two electric hoists 14 working synchronously, and during the lifting process, the I-beam one 4 and the I-beam two 5 slide in the channel steel 16, to prevent the deviation, and the anti-collision baffle 18 and the anti-falling baffle 19 can effectively ensure the safety during the lifting process, and after reaching the specified position, the support body 1 is effectively fixed with the structure surface by the anchoring structure, to ensure that the entire operation platform is in a fixed state at the position, and in order to ensure that the patterned steel plate two 3 after expansion has a certain strength, the application is provided with the following settings:

[0037] The spacer plate 8 is fixedly installed on the support body 1, and a plurality of clamping seats 9 are fixedly installed on the spacer plate 8. The connecting shaft 10 is fixedly installed on the lower surface of the second patterned steel plate 3. The reinforcing mechanism 11 is arranged between the clamping seat 9 and the connecting shaft 10. As a further limitation in the application, the reinforcing mechanism 11 comprises a limiting sleeve 111 rotatably connected with the clamping seat 9, a sliding rod frame 112 installed in the limiting sleeve 111, wherein the sliding rod frame 112 is limitedly slid between the inner walls of the limiting sleeve 111, and a hinged seat body 113 fixedly installed at the end of the sliding rod frame 112, and the hinged seat body 113 is rotatably connected with the end of the connecting shaft 10. A plurality of connecting seats 114 are fixedly installed on the inner wall of the support body 1, and a connecting plate frame 115 rotatably connected with the connecting seat 114 is installed on the connecting seat 114. The fixed seat 116 is fixedly installed on one side of the limiting sleeve 111, and the reinforcing rod frame 117 is connected between the fixed seat 116 and the connecting plate frame 115, and the two ends of the reinforcing rod frame 117 are rotatably connected with the fixed seat 116 and the connecting plate frame 115, respectively.

[0038] Specifically, when the positions of the second patterned steel plate 3 and the first patterned steel plate 2 are adjusted, the connecting shaft 10 on the lower surface of the second patterned steel plate 3 drives the hinged seat body 113 to be adjusted in position, and the hinged seat body 113 drives the sliding rod frame 112 to move synchronously, i.e. the sliding rod frame 112 is adjusted in position in the limiting sleeve 111. During the position adjustment of the sliding rod frame 112 in the limiting sleeve 111, the limiting sleeve 111 is adjusted in angle under the action of the seat body, and the reinforcing rod frame 117 gives the limiting sleeve 111 a certain supporting force under the action of the connecting plate frame 115 and the connecting seat 114, so as to ensure that the second patterned steel plate 3 still has a certain supporting strength after the position adjustment. It is further explained that the first patterned steel plate 2 is located below the second patterned steel plate 3 and supports the second patterned steel plate 3. The support body 1 supports the first patterned steel plate 2, and thus the supporting strength of the first patterned steel plate 2 is greater than that of the second patterned steel plate 3 after the position adjustment. Therefore, the first patterned steel plate 2 is not reinforced in the application. When the construction is performed on an elevator shaft with a large length size, in order to ensure the safety of the elevator shaft, the first patterned steel plate 2 can also be reinforced.

[0039] The adjusted support body 1 is fixed between the structure layer through the anchor, in order to prevent the vibration force generated in the construction process from causing the patterned steel plate 1 and the patterned steel plate 2 to appear in a shaking state, the patterned steel plate 1 and the patterned steel plate 2 after movement are further limited, that is, the lower surface of the patterned steel plate 1 is symmetrically and fixedly provided with a placing frame 12, a plurality of sliding frames 121 are parallelly arranged in the placing frame 12, and the plurality of sliding frames 121 are all in sliding connection with the inner wall of the placing frame 12, the top of each sliding frame 121 penetrates the inner wall of the patterned steel plate 1 and is fixedly connected with the bottom of the patterned steel plate 2, and the top of the sliding frame 121 is in sliding connection with the inner wall of the patterned steel plate 1, that is, when the patterned steel plate 1 and the patterned steel plate 2 are adjusted in position, the plurality of sliding frames 121 are driven to be adjusted in position in the placing frame 12, an action plate frame 122 in sliding connection with the inner wall of the sliding frame 121 is arranged in the sliding frame 121, an extension column 123 is fixedly arranged on one side of the action plate frame 122, and the end of the extension column 123 penetrates the inner wall of the sliding frame 121 and extends to the outside, wherein an inclined groove 124 is arranged on the action plate frame 122, an action column 125 is arranged in the sliding frame 121, and the two ends of the action column 125 penetrate the inner walls of the two ends of the sliding frame 121 and extend to the outside, a rope a 126 is connected between the ends of the two adjacent action columns 125, a sliding column 127 is arranged on the action column 125, and the end of the sliding column 127 is located in the inclined groove 124 and is limited to slide therein, and a reset spring 128 is connected to the side, away from the extension column 123, of the action plate frame 122, the end of the reset spring 128 is connected with the side wall of the sliding frame 121, a plurality of clamping plates 129 are fixedly arranged on the inner walls of the two sides of the placing frame 12, and the distance between the two adjacent clamping plates 129 is equal to the diameter of the extension column 123.

[0040] Specifically, in the initial state (that is, when the patterned steel plate 1 and the patterned steel plate 2 are adjusted in position), the end of the extension column 123 is located on one side of the clamping plate 129 and is not between the two adjacent clamping plates 129, and further, although the sizes of different elevator shafts are different, generally, the size of the elevator shaft is set within a constant limit value, after the patterned steel plate 1 and the patterned steel plate 2 are adjusted in position, the action column 125 is pulled outward, the end of the sliding column 127 on the action column 125 is limited to slide in the inclined groove 124, the action plate frame 122 is caused to slide in the sliding frame 121 by the action on the inclined groove 124, at this time, the extension column 123 on one side of the action plate frame 122 enters between the clamping plates 129, and the reset spring 128 is in a stretched state, after the patterned steel plate 1 and the patterned steel plate 2 are adjusted in position, the end of the extension column 123 is located between the two adjacent clamping plates 129, and further, when the action column 125 is pulled outward, the rope a 126 drives the other plurality of action columns 125 to move synchronously.
