DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] like Figures 1 to 6 As shown, a construction device for installing a chassis on a pole body comprises: a lower locking ring 2, an upper locking ring 1 and a lifting component.

[0019] The lifting component includes a supporting ladder section 3 and a lifting ladder section 4.

[0020] The supporting ladder section 3 includes a pair of side tubes 31 arranged in parallel. The side tubes 31 are connected by a plurality of spaced cross beams 32 . A screw rod 33 is arranged in parallel between the two side tubes 31 , and the screw rod 33 passes through the cross beam 32 .

[0021] The elevator section 4 includes two side rods 41, and the two side rods 41 are respectively and parallelly arranged in the two side tubes 31. The opposite sides of the two side rods 41 are hinged with multiple cantilevers 42 along the length direction of the side rods 41. The upper ends of the two side rods 41 are connected with a support frame 5 for fixing the chassis. Specifically, the chassis can be fixed to the support frame 5 by bolting or rope tying. Because the main function of the support frame 5 is to fix the chassis, as long as the chassis can be stably and firmly fixed, the specific structure of the support frame 5 can be adaptively designed according to the structure of the chassis. Specifically, the support frame 5 can be set to a flat plate structure, and can also be set to a U-shaped cross-section structure. Specifically, the opening of the U-shaped cross-section can be facing the rod body or the top of the elevator section 4. The upper end of the screw rod 33 is connected to the upper end of the elevator section 4. In this embodiment, a cross bar is provided at the top of the two side rods 41 for fixedly connecting the two side rods 41. The screw rod 33 can be connected to the cross bar. As another connection structure, the upper end of the screw rod 33 can also be connected to the bottom of the support frame 5.

[0022] The screw 33 is arranged to move along the axis direction, and is used to control the depth of the side rod 41 inserted into the side tube 31, thereby controlling the distance between the support frame 5 and the bottom of the support ladder section 3. Specifically, there are multiple ways to move the screw 33. First, the screw 33 and the cross beam 32 can be connected by a thread, and the top of the screw 33 and the lifting ladder section 4 are connected by rotation. When the screw 33 is rotated, the screw 33 can be driven to move along the axis. The screw 33 can be rotated manually or driven by a motor. The motor driving the screw 33 to rotate is set on the lifting ladder section 4; second, Figure 4 , Figure 6 The worm 33 is engaged with the worm gear 34 and the worm gear 35 is engaged with the worm gear 34. The worm gear 35 is connected to the worm gear 34 by manual rotation or by a motor. The worm gear 34 is provided with a threaded hole coaxially therein for connecting the screw 33. The upper end of the screw 33 is fixedly connected to the elevator section 4. When in use, the worm gear 35 can be driven to rotate by rotating the worm gear 34. When the worm gear 34 rotates, the screw 33 can be driven to move along the axis. This transmission mechanism has two self-locking structures for preventing the elevator section 4 from falling. One is to use the threaded connection structure between the screw 33 and the worm gear 34 to prevent the screw 33 from moving downward. The other is to use the worm gear 35 to lock the worm gear 34 to prevent the worm gear 34 from rotating by itself. And the above-mentioned driving mechanism can make the elevator section 4 rise smoothly and achieve the purpose of fine-tuning the height of the elevator section 4. When the side rod 41 moves toward the lower end of the side tube 31, the cantilever 42 contacts the upper end of the side tube 31, and the cantilever 42 swings around the hinge axis toward the upper end of the side rod 41. Figure 6 As shown, when the hinged portion of the cantilever 42 and the side rod 41 is inserted into the side tube 31, the cantilever 42 and the side rod 41 are inserted into the side tube 31 together; Figures 3 to 5As shown, when the hinged portion of the cantilever 42 and the side rod 41 protrudes from the top of the side tube 31, the cantilever 42 is suspended on the side rod 41, and the angle between the cantilever 42 and the upper section of the side rod 41 is less than or equal to 90 degrees. Specifically, a stopper 411 can be provided on the side rod 41 at a position corresponding to the lower portion of the cantilever 42 to limit the downward swing angle of the cantilever 422, so that the cantilever 42 meets the requirement that the angle between the cantilever 42 and the upper section of the side rod 41 is less than or equal to 90 degrees when in the suspended state.

[0023] The upper locking ring 1 and the lower locking ring 2 are both annular structures.

[0024] The lower locking ring 2 is used to connect the lower end of the rod body, and the lower end of the supporting ladder section 3 is rotatably connected to the lower locking ring 2. When in use, the axis of rotation between the supporting ladder section 3 and the lower locking ring 2 is perpendicular to the axis of the rod body and the screw 33, and parallel to the plane formed by the two side tubes 31.

[0025] The upper locking ring 1 is connected to a predetermined height of the rod body, and the upper locking ring 1 is connected to the middle section or the upper end of the supporting ladder section 3 via a hand chain hoist 6 .

[0026] like Figure 7 As shown, the method for installing the chassis using the above-mentioned construction device includes the following steps: S1: Arrange lifting components, such as Figure 1 As shown, the lower locking ring 2 is connected to the lower end of the pole body, and the pole body is a lamp pole, a telephone pole or a signal pole, etc. The support frame 5 and the top of the supporting ladder section 3 are adjusted to the minimum distance to reduce the length of the force arm when the lifting component is flipped, and the upper locking ring 1 is connected to a predetermined height on the pole body. Preferably, the upper locking ring 1 can be connected to a height position that can be directly operated by hand when a person is standing, and the upper locking ring 1 is connected to the supporting ladder section 3 using a hand winch 6.

[0027] S2: Fixed chassis, such as Figure 1 As shown, the chassis is fixed on the support frame 5, with the side of the chassis used to connect to the rod body facing upwards; S3: Flip the lifting parts, such as Figure 2 As shown, by manually pulling the hand chain hoist 6, the lifting component is turned upward until the mounting surface of the chassis contacts the rod body; S4: Adjust the height of the chassis, such as Figure 3 As shown, by moving the screw rod 33 upward, the chassis is adjusted to a predetermined height position, and the elevator section 4 and the cantilever 42 will rise together with the screw rod 33. When the hinged portion of the cantilever 42 and the side rod 41 protrudes from the top of the side tube 31, the cantilever 42 is suspended on the side rod 41; S5: Lock the chassis. The operator climbs up to the chassis installation location by stepping on the crossbeam 32 and the cantilever 42, installs and locks the chassis, and removes the connection between the chassis and the support frame 5.

[0028] Preferably, an elastic member 43 is provided between the cantilever 42 and the corresponding side rod 41. When the cantilever 42 and the side rod 41 are inserted into the side tube 31 together, the elastic member 43 is compressed, so that when the hinged portion of the cantilever 42 and the side rod 41 protrudes from the top of the side tube 31, the cantilever 42 can be quickly popped open by the elastic member 43, so that the cantilever 42 is automatically suspended on the side rod 41, which is convenient for the operator to climb directly. When the cantilever 42 is inserted into the side tube 31, the elastic member 43 is used to prop the cantilever 42 open relative to the side rod 41, so that the cantilever 42 is pressed against the inner wall of the side tube 31 to eliminate the influence of the gap between the cantilever 42 and the side rod 41 and the side tube 31, thereby reducing the shaking between the lifting ladder section 4 and the supporting ladder section 3, and improving the stability of the lifting component when in use.

[0029] Further preferably, Figure 4 , Figure 6 As shown, the elastic member 43 is a spring sheet structure, which is installed above the hinged portion of the cantilever 42 and the side rod 41 and is connected to the side rod 41. The elastic member 43 is installed at this corner to prevent the operator from stepping on the elastic member 43 and to prevent the elastic member 43 from affecting the operator's climbing.

[0030] As further preferred, preferably, Figure 4 , Figure 6 As shown, the lower end of the elastic member 43 is connected to the side rod 41, and the angle between the upper end of the elastic member 43 and the side rod 41 is opened upward to prevent the cantilever 42 from being stuck and causing the cantilever 42 to be unable to be smoothly inserted into the side tube 31.

[0031] Preferably, Figures 4 to 6 As shown, the cantilevers 42 on the two side rods 41 are arranged in pairs. When the cantilevers 42 are in a suspended state, the end faces of the two cantilevers 42 arranged in pairs at opposite ends abut against each other, and the angle between the two cantilevers 42 is less than 180 degrees, and the angle between the cantilever 42 and the upper section of the corresponding side rod 41 is less than 90 degrees. The ends of the cantilevers 42 that abut against each other are provided with avoidance grooves 421 for passing the screw rod 33 to prevent the screw rod 33 from being affected in its movement. The purpose of this structural design is mainly to enable the two cantilevers 42 arranged in pairs to form a bridge structure, support each other, and prevent the cantilevers 42 from swinging downward, thereby improving the load-bearing capacity of the cantilevers 42. At the same time, the reaction force generated by the two cantilevers 42 when overlapping the side rod 41 is used to press the side rod 41 against the side wall of the side tube 31, thereby effectively preventing the side rod 41 from shaking in the side tube 31, thereby further improving the stability of the lifting component when in use.

[0032] Preferably, the side tube 31 is a rectangular tube structure, and the side rod 41 and the cantilever 42 are both rectangular rods or rectangular tube structures.

[0033] Preferably, Figure 2 , Figure 3As shown, a support member 7 is provided between the lower locking ring 2 and the support step 3, and its two ends are respectively connected to the lower locking ring 2 and the support step 3 for rotation, and the axes of rotation of the two ends are perpendicular to the axes of the rod body and the screw 33, and are parallel to the plane formed by the two side tubes 31. The distance between the two ends of the support member 7 has an adjustment function, which is used to adjust the spacing between the lower locking ring 2 and the support step 3, so as to adjust the distance and angle between the chassis and the rod body during installation. Specifically, the support member 7 is designed as a telescopic rod structure, and a locking screw is used to lock the thickness adjustment state. It can also be designed as a structure in which a threaded rod and a threaded pipe cooperate. By rotating the threaded pipe or the threaded rod, the distance between the two ends of the support member 7 formed by the threaded pipe and the threaded rod can be adjusted, and the threaded connection has a self-locking function, which can also reduce the use of locking screws, improve the convenience of operation, and the threaded pipe or the threaded rod can also be smoothly rotated during the installation process, which is more convenient to use.

[0034] Preferably, Figure 3 , Figure 5 As shown, the lower ends of the two side tubes 31 are provided with rollers 36. When the lifting component is swung upward, the rollers 36 and the ground rolling structure are utilized to improve the smoothness of the lifting component when swinging upward.

[0035] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
