DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, an elevator shaft support device for elevator installation includes a support frame 1, an operating platform 2, a clamping seat 3 and a connecting piece 4.

[0021] The support frame 1 includes two fixed columns 101, and a plurality of fixed rods 102 are fixedly connected between the two fixed columns 101. A support column 103 is provided between the lower rear end of the fixed column 101 and the operating table 2. The fixed column 101 and the support column 103 are both hollow structures. A positioning cylinder 104 is provided above the fixed column 101. A positioning column 105 inserted into the inside of the fixed column 101 is fixedly connected to the bottom of the positioning cylinder 104, and a movable column 106 is inserted into the top of the support column 103.

[0022] The operating table 2 includes a rectangular frame 201 , a support plate 202 is mounted on the top of the rectangular frame 201 , a plurality of horizontal plates 203 are fixedly connected inside the rectangular frame 201 , and a limiting column 204 inserted into the positioning cylinder 104 is fixedly connected to the bottom of one end of the rectangular frame 201 .

[0023] The support column 103, the positioning cylinder 104, and the upper side of the support column 103 are all provided with threaded holes, in which screws are installed, and the ends of the screws abut against the positioning column 105, the limiting column 204, or the movable column 106. When the screws are tightened, the positioning column 105 can be fixed inside the support column 103, the limiting column 204 can be fixed inside the positioning cylinder 104, and the movable column 106 can be fixed inside the support column 103.

[0024] The bottom of the support column 103 is rotatably connected to the fixed column 101 through the connecting member 4, and the top of the movable column 106 is rotatably connected to the cross plate 203 through the connecting member 4. The connecting member 4 includes a U-shaped frame 401 and a connecting block 402 movably arranged on the inner side of the U-shaped frame 401. Through holes are provided on the U-shaped frame 401 and the connecting block 402. Bolts 403 are installed in the through holes, and nuts are installed on the bolts 403. The U-shaped frame 401 is fixedly installed on the ends of the positioning column 105 and the movable column 106, and the connecting block 402 is fixedly installed on the fixed column 101 and the cross plate 203.

[0025] There are two clamping seats 3, which are fixedly mounted on the lower front end of the fixed column 101. The clamping seats 3 are clamped on the lower floor of the elevator shaft opening as the lower support point of the supporting device.

[0026] In specific use, the limiting column 204 at the bottom of the rectangular frame 201 is inserted into the positioning cylinder 104 and tightened with screws to secure it. The depth of the positioning column 105 inserted into the fixed column 101 is adjusted. When the positioning column 105 moves up and down along the fixed column 101, the support column 103 rotates around the connecting piece 4 at its connection with the fixed column 101, and the movable column 106 moves along the support column 103. After the position of the positioning column 105 is adjusted, the screws are tightened to secure the positioning column 105 and the movable column 106 respectively. The spacing between the operating platform 2 and the clamping seat 3 can be adjusted, thereby making the device suitable for elevator shafts of different floor heights. The various components of the device are connected by screws and bolts, making it easy to assemble and disassemble and convenient for transportation.
