Description

TECHNICAL FIELD

[0001] The present application belongs to the field of outdoor control cabinet and case construction installation tools, and particularly relates to a construction device and method for installing a case on a pole body. BACKGROUND

[0002] In urban construction, various devices such as communication devices, lighting devices, signal lights, monitoring devices, and signal transceiver devices need to be set in public places such as roads, parks, and communities, and some of the devices need to be set on corresponding installation carriers such as pole bodies during configuration. The installation carrier is usually a pole structure, including a street lamp pole, a signal light pole, etc.

[0003] In the existing construction and installation process, a climbing car or hoisting equipment is usually needed to install the case to the predetermined height position of the pole body, so large mechanical equipment needs to be used during installation, which not only increases the construction cost but also makes it inconvenient for the climbing car or hoisting equipment to enter due to the limited area. SUMMARY

[0004] To solve the problems in the prior art, the present application provides a construction device and method for installing a case on a pole body, which can install the case to the predetermined height of the pole body without using large equipment, has a simple overall structure, is easy to operate, and can be used in limited areas.

[0005] To achieve the purpose of the present application, the following solutions are adopted:

[0006] A construction device for installing a case on a pole body comprises a lower locking ring, an upper locking ring, and a lifting component.

[0007] The lifting component comprises a support ladder section and a lifting ladder section.

[0008] The support ladder section comprises a pair of parallel side pipes connected by a plurality of horizontally arranged cross beams, and a screw rod is arranged between the two side pipes in parallel.

[0009] The lifting ladder section comprises two side rods arranged in parallel in the two side pipes, and a plurality of cantilevers are arranged on the opposite side of the two side rods along the length direction of the side rods.

[0010] The screw is set to move along the axial direction to control the depth of the side rod inserted into the side tube. During the movement of the side rod towards the lower end of the side tube, when the cantilever contacts the upper end of the side tube, the cantilever swings around the hinge axis to the upper end of the side rod. When the hinge part of the cantilever and the side rod is inserted into the side tube, the cantilever and the side rod are inserted into the side tube together. When the hinge part of the cantilever and the side rod protrudes from the top of the side tube, the cantilever is suspended on the side rod, and the included angle between the cantilever and the upper part of the side rod is less than or equal to 90 degrees.

[0011] Both the upper and lower locking rings are ring structures;

[0012] The lower locking ring is used to connect the lower end of the rod body, and the lower end of the supporting ladder section is rotatably connected to the lower locking ring;

[0013] The locking ring is connected to the predetermined height of the pole, and the locking ring is connected to the middle or upper end of the supporting ladder section by a hand-operated hoist.

[0014] A method for mounting a chassis on a pole, utilizing the aforementioned construction device for mounting a chassis on a pole, includes the following steps:

[0015] S1: Arrange the lifting components, connect the lower locking ring to the lower end of the pole, adjust the distance between the support frame and the top of the support ladder to the minimum, connect the upper locking ring to the pole at a predetermined height, and use a hand chain hoist to connect the upper locking ring to the support ladder.

[0016] S2: Fix the chassis, fix the chassis to the support frame, with the side of the chassis that is connected to the pole facing upwards;

[0017] S3: Tilting and lifting components: The lifting components are tilted upward by manually pulling the hand chain hoist until the mounting surface of the machine box contacts the rod.

[0018] S4: Adjust the height of the chassis. By moving the screw upwards, the chassis is adjusted to the predetermined height position. The lifting section and cantilever will rise together with the screw. When the hinge part of the cantilever and the side rod protrudes from the top of the side tube, the cantilever is suspended on the side rod.

[0019] S5: Lock the chassis. The operator climbs up to the chassis installation location by stepping on the crossbeams and cantilever, installs and locks the chassis, and disconnects the connection between the chassis and the support frame.

[0020] The beneficial effects of this invention are as follows: This solution mainly includes an upper locking ring, a lower locking ring, a supporting ladder section, and a lifting ladder section. The overall structure has fewer components, is simple, and is easy to operate. It can replace the aerial work platform for installing the machine housing on the pole, effectively reducing construction costs. The lifting component has a height adjustment function, allowing the machine housing to be installed at a predetermined height. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0031] like Figures 1 to 6 As shown, a construction device for installing a machine box on a pole includes: a lower locking ring 2, an upper locking ring 1, and a lifting component.

[0032] The lifting components include a support ladder section 3 and a lifting ladder section 4.

[0033] The supporting ladder section 3 includes a pair of parallel side tubes 31, which are connected by multiple spaced crossbeams 32. A screw 33 is provided parallel between the two side tubes 31 and passes through the crossbeams 32.

[0034] The lifting escalator section 4 includes two side rods 41, which are parallel to each other and pass through two side tubes 31. Multiple cantilever arms 42 are hinged to the opposite side of each side rod 41 along its length. A support frame 5 is connected to the upper end of each side rod 41 for fixing the chassis. Specifically, the chassis can be fixed to the support frame 5 by bolts or ropes. Since the main function of the support frame 5 is to fix the chassis, its specific structure can be adapted to the chassis structure as long as it can stably and securely secure the chassis. Specifically, the support frame 5 can be a flat plate structure or a U-shaped cross-section structure. Specifically, the opening of the U-shaped cross-section can face upwards towards the rods or the lifting escalator section 4. The upper end of the screw 33 is connected to the upper end of the lifting section 4. In this embodiment, a crossbar is provided at the top of the two side rods 41 for fixing the two side rods 41. The screw 33 can be connected to the crossbar as another connection structure, or the upper end of the screw 33 can be connected to the bottom of the support frame 5.

[0035] The screw 33 is movable along the axial direction 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, the screw 33 can move in several ways. First, the screw 33 can be threadedly connected to the crossbeam 32, and the top of the screw 33 can be rotatably connected to the lifting ladder section 4. When the screw 33 is rotated, it can be driven to move along the axial direction. The screw 33 can be rotated manually or driven by a motor, and the motor driving the screw 33 is located in the lifting ladder section 4. Second, such as... Figure 4 , Figure 6 As shown, a worm gear 34 is rotatably mounted at the bottom of the crossbeam 32 at the uppermost end of the side tube 31, and a worm 35 is engaged with it. The worm 35 is rotatably connected to the crossbeam 32 on which the worm gear 34 is mounted. The worm 35 is manually rotated or driven by a motor. The worm gear 34 has a threaded hole coaxially inside, which is used to connect a screw 33. The upper end of the screw 33 is fixedly connected to the lifting section 4. In use, rotating the worm 35 will drive the worm gear 34 to rotate. When the worm gear 34 rotates, it will drive the screw 33 to move along the axis. This transmission mechanism has two self-locking structures to prevent the lifting section 4 from falling. One is the threaded connection structure between the screw 33 and the worm gear 34 to prevent the screw 33 from moving downward. The other is that the worm gear 35 locks the worm gear 34 to prevent the worm gear 34 from rotating on its own. Furthermore, the above-mentioned drive mechanism can make the lifting section 4 rise smoothly and can achieve the purpose of fine adjustment of the height of the lifting section 4. As the side rod 41 moves towards the lower end of the side tube 31, when the cantilever 42 contacts the upper end of the side tube 31, the cantilever 42 swings around the hinge axis towards the upper end of the side rod 41. Figure 6 As shown, when the hinged joint between 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; as 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 stop 411 can be provided on the side rod 41 at a position corresponding to the lower part of the cantilever 42 to limit the downward swing angle of the cantilever 422, thereby ensuring 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 the cantilever 42 is suspended.

[0036] Both the upper locking ring 1 and the lower locking ring 2 are ring structures.

[0037] The lower locking ring 2 is used to connect the lower end of the rod body. The lower end of the support ladder section 3 is rotatably connected to the lower locking ring 2. When in use, the axis of rotation between the support 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.

[0038] The locking ring 1 is connected to the predetermined height of the pole, and the locking ring 1 is connected to the middle or upper end of the supporting ladder section 3 by a hand chain hoist 6.

[0039] like Figure 7 As shown, the method for installing the chassis using the above-mentioned construction device includes the following steps:

[0040] S1: Arrange lifting components, such as Figure 1 As shown, the lower locking ring 2 is connected to the lower end of the pole, which can be a light pole, utility pole, or signal pole, etc. The distance between the support frame 5 and the top of the support ladder section 3 is adjusted to the minimum to reduce the lever arm length when the lifting and tilting components are tilted. The upper locking ring 1 is connected to the pole at a predetermined height. 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. The upper locking ring 1 is connected to the support ladder section 3 using a hand chain hoist 6.

[0041] S2: Fixed chassis, such as Figure 1 As shown, the chassis is fixed on the support frame 5, with the side of the chassis that is connected to the pole facing upwards;

[0042] S3: Tilting and lifting components, such as Figure 2 As shown, by manually pulling the hand chain hoist 6, the lifting component is flipped upward until the mounting surface of the machine box contacts the rod.

[0043] S4: Adjust the chassis height, such as Figure 3 As shown, by moving the screw 33 upward, the chassis is adjusted to a predetermined height position, and the lifting section 4 and the cantilever 42 will rise together with the screw 33. When the hinge part 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.

[0044] S5: Lock the chassis. The operator climbs up to the chassis installation location by stepping on the crossbeam 32 and cantilever 42, installs and locks the chassis, and disconnects the connection between the chassis and the support frame 5.

[0045] Preferably, an elastic element 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 element 43 is compressed so that when the hinge part of the cantilever 42 and the side rod 41 protrudes from the top of the side tube 31, the elastic element 43 can quickly spring the cantilever 42 open, so that the cantilever 42 is automatically suspended on the side rod 41, which is convenient for the operator to climb and use directly. When the cantilever 42 is inserted into the side tube 31, the elastic element 43 can expand the cantilever 42 relative to the side rod 41, so that the cantilever 42 is pressed against the inner wall of the side tube 31, thereby eliminating the influence of the gap between the cantilever 42 and the side rod 41 and the side tube 31, thereby reducing the sway between the lifting ladder section 4 and the supporting ladder section 3 and improving the stability of the lifting components during use.

[0046] Further preferred, such as Figure 4 , Figure 6 As shown, the elastic element 43 is a spring sheet structure, which is installed above the hinge part of the cantilever 42 and the side rod 41 and connected to the side rod 41. The elastic element 43 is installed at this corner to prevent the operator from stepping on the elastic element 43 and to prevent the elastic element 43 from affecting the operator's climbing.

[0047] As a further preferred option, such as... Figure 4 , Figure 6 As shown, the lower end of the elastic element 43 is connected to the side rod 41, and the opening of the upper end of the elastic element 43 and the side rod 41 faces upward to prevent the cantilever 42 from getting stuck, which would prevent the cantilever 42 from being inserted smoothly into the side tube 31.

[0048] Preferred, such as Figures 4 to 6 As shown, the cantilever arms 42 on the two side rods 41 are arranged in pairs. When the cantilever arms 42 are suspended, the end faces of the two cantilever arms 42 abut against each other, and the included angle between the two cantilever arms 42 is less than 180 degrees. The included angle between the cantilever arm 42 and the upper section of the corresponding side rod 41 is less than 90 degrees. Each abutting end of the cantilever arm 42 has a clearance groove 421 for passing through the screw 33 to prevent interference with the movement of the screw 33. The purpose of this structural design is mainly to make the two cantilever arms 42 form a bridging structure, supporting each other and preventing the cantilever arms 42 from swinging downwards, thereby improving the load-bearing capacity of the cantilever arms 42. At the same time, the reaction force generated on the side rod 41 when the two cantilever arms 42 overlap presses the side rod 41 tightly against the side wall of the side tube 31, effectively preventing the side rod 41 from swaying inside the side tube 31, thereby further improving the stability of the lifting component during use.

[0049] 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.

[0050] Preferred, such as Figure 2 , Figure 3 As shown, a support member 7 is provided between the lower locking ring 2 and the supporting ladder section 3. Its two ends are rotatably connected to the lower locking ring 2 and the supporting ladder section 3, respectively. The axes of rotation at both ends are perpendicular to the axes of the rod and the screw 33, and parallel to the plane formed by the two side tubes 31. The distance between the two ends of the support member 7 is adjustable, used to adjust the gap between the lower locking ring 2 and the supporting ladder section 3, so as to adjust the distance and angle between the chassis and the rod 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 of threaded rod and threaded tube. By rotating the threaded tube or threaded rod, the distance between the two ends of the support member 7 formed by the threaded tube and threaded rod can be adjusted. The threaded connection has a self-locking function, reduces the use of locking screws, improves operational convenience, and allows for smooth rotation of the threaded tube or threaded rod during installation, making it more convenient to use.

[0051] Preferred, such as Figure 3 , Figure 5 As shown, rollers 36 are provided at the lower ends of both side tubes 31. When the lifting component swings upward, the rollers 36 and the ground rolling structure can improve the smoothness of the lifting component swinging upward.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
