A portable multi-functional support device for temporary outdoor power construction operations

Abstract

This invention relates to the field of tools and equipment for power system construction operations. The invention discloses a portable multi-functional support device for temporary outdoor power construction operations, including a support chassis with a hollow rod fixedly connected to the top surface of the chassis. The problem this invention aims to solve is the need for portable lifting supports and overhead line suspension during temporary outdoor construction operations in power systems. The invention consists of a support fixing mechanism and a control mechanism. The device resets two threaded sleeves by rotating the internal threaded tube clockwise, causing the deflection plate to engage inside the storage slot. When the lower threaded sleeve moves downwards, the tension spring causes the rectangular frame to reset, leading to the deflection and reset of the hinge rod. This, in turn, causes the compression plate to deflect and reset. During the reset of the rectangular frame, the slot engages and locks with one side of the compression plate, allowing the slot to be stored within the rectangular frame. This facilitates folding and storage of the device, reducing its overall size and making it easier to transport.

Description

Technical Field

[0001] This invention relates to the field of tools and equipment for power system construction operations, specifically a portable multi-functional support device for temporary outdoor power construction operations. Background Technology

[0002] When power systems inspect and maintain transmission and distribution lines and electrical equipment, maintenance personnel often need to work at heights. Some equipment requires placement at elevated positions or with sufficient clearance from the ground to prevent moisture or water damage. Currently, power system maintenance personnel carry insulated ladders for outdoor work. However, insulated ladders have a small load-bearing capacity, requiring multiple ladders to be erected together. This results in very large equipment that is difficult to operate and store. Outdoor work vehicles typically have limited space for tools and equipment, making their large size difficult to move around. This is especially problematic in mountainous and hilly areas, where traditional ladders increase the difficulty of manually transporting tools. Therefore, there is an urgent need for convenient and reliable access and support equipment.

[0003] Furthermore, during power system maintenance and measurement, it is often necessary to connect and string cables to equipment. Since some cables need to be suspended above the ground, there is a lack of cable support equipment at the work site, and a large number of supports are required when the cables are long. Previously, tying the cables to insulated ladders or nearby trees was used, which posed a risk of tipping over and other safety hazards, and did not comply with power construction safety regulations and requirements.

[0004] Therefore, considering the need for power maintenance personnel to climb to heights and for power equipment and connecting cables to be suspended in the air during the maintenance and construction of power transmission and distribution lines and power equipment, it is particularly necessary to develop a new type of support device that is sturdy, height-adjustable, and portable for storage and transportation. Portable multi-functional support devices for temporary outdoor power construction operations undoubtedly have wide application value. Summary of the Invention

[0005] The purpose of this invention is to provide a portable multi-functional support device for temporary outdoor power construction operations, thereby solving the technical bottlenecks faced by power maintenance personnel in climbing heights and suspending power equipment and connecting cables during the maintenance and construction of power transmission and distribution lines and power equipment, as mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a portable multi-functional support device for temporary outdoor power construction operations, comprising a support chassis, a hollow rod fixedly connected to the top surface of the support chassis, and reinforcing ribs fixedly connected to the side surface of the hollow rod;

[0006] A groove is provided at the bottom of the side of the hollow rod, and a support and fixing mechanism is hinged to the side of the inner wall of the groove. An adjustment mechanism is fixedly sleeved in the middle of the side of the hollow rod, and the lower side of the adjustment mechanism abuts and is locked in place with the side of the support and fixing mechanism.

[0007] The upper end of the hollow rod is fixedly connected to a rectangular rod, and the lower side of the rectangular rod is electrically connected to the supporting chassis. A storage groove is provided on the side of the rectangular rod, and a deflection plate is hinged to the side of the storage groove. A compression spring is fixedly connected to the side of the deflection plate, and the end of the compression spring away from the deflection plate is fixedly connected to the side of the inner wall of the storage groove.

[0008] Preferably, the support and fixing mechanism includes an extrusion plate, one side of which is hinged to the side of the inner wall of the groove, a rectangular frame is movably sleeved on the side of the extrusion plate, a hinge rod is hinged to the upper side of the rectangular frame, and the end of the hinge rod away from the rectangular frame is slidably connected to the side of the inner wall of the groove.

[0009] A limiting plate overlaps the lower side of the extrusion plate, and the side of the limiting plate is fixedly connected to the side of the supporting chassis. A tension spring is fixedly connected to the side of the extrusion plate, and the end of the tension spring away from the extrusion plate is fixedly connected to the side of the rectangular frame.

[0010] Preferably, a plug is movably inserted into the bottom surface of the inner wall of the rectangular frame, and a compression spring is fixedly connected to the top surface of the plug, with the upper end of the compression spring fixedly connected to the top surface of the inner wall of the rectangular frame.

[0011] The side of the insert has a slot.

[0012] Preferably, the control mechanism includes a fixed bearing, which is fixedly sleeved on the middle part of the side of the hollow rod. An internally threaded tube is fixedly sleeved on the side of the fixed bearing. Threaded sleeves are rotatably connected to both the upper and lower sides of the inner wall of the internally threaded tube. The inner wall of the threaded sleeve is slidably connected to the side of the hollow rod and the side of the reinforcing rib. The lower side of the inner wall of the lower threaded sleeve is in contact with and locked to the side of the hinge rod.

[0013] Preferably, a conductive wire is fixedly connected to the lower side of the rectangular rod, and one end of the conductive wire is fixedly connected to the input end of the support chassis. This can ensure the safe and reliable grounding of some live equipment during support, avoiding the risk of electric shock to construction workers from live equipment.

[0014] Preferably, the bottom surface of the supporting chassis is fixedly connected with a plug, and the plug is conical in shape.

[0015] Preferably, the number of threaded sleeves is two, and the direction of the thread helix on the side of the two threaded sleeves is the same.

[0016] Preferably, the side of the internally threaded tube is wrapped with an insulating rubber sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In this invention, rotating the internal threaded tube clockwise causes the two threaded sleeves to reset, so that the deflection plate is locked inside the storage slot. When the lower threaded sleeve moves down, the tension spring causes the rectangular frame to reset, causing the hinge rod to deflect and reset. The rectangular frame causes the extrusion plate to deflect and reset. When the rectangular frame resets, the slot and one side of the extrusion plate abut and lock in place, so that the slot is stored in the rectangular frame. This makes it easy to fold and store the device, reduce the overall volume of the device, and facilitate the transportation of the device.

[0019] In this invention, rotating the internally threaded tube causes it to rotate counterclockwise, which in turn moves the two threaded sleeves downwards. This causes the upper threaded sleeve to move downwards, and under the restoring force of the compression spring, the deflection plate unfolds, maintaining a firm connection. This design significantly increases the load-bearing area at the top of the support device, enabling support for large panels and allowing for the suspension of wires of various diameters, measuring wires, and other connecting cables.

[0020] In this invention, when the lower threaded sleeve is moved downward by rotating the internal threaded tube, the lower threaded sleeve squeezes the hinge rod, causing one end of the hinge rod to move downward in the groove, causing the rectangular frame and the extrusion plate to deflect parallel to the ground. At the same time as the rectangular frame deflects, the rectangular frame slides on the side of the extrusion plate, increasing the overall length of the extrusion plate and the rectangular frame, thereby increasing the contact area between the device and the ground and ensuring the stability of the device fixed on the ground.

[0021] In this invention, when the rectangular frame slides on the side of the extrusion plate, it causes one side of the extrusion plate to separate from the side of the slot. Under the action of the compression spring's restoring force, the insert block pops out from inside the rectangular frame and is inserted into the soil at the designated location, further increasing the stability of the device fixed on the ground.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 5 The present invention provides a technical solution: a portable multi-functional support device for temporary outdoor power construction operations, including a support base 1, a hollow rod 2 fixedly connected to the top surface of the support base 1, and a reinforcing rib 3 fixedly connected to the side of the hollow rod 2;

[0030] A groove 4 is provided at the bottom of the side of the hollow rod 2. A support and fixing mechanism 5 is hinged to the side of the inner wall of the groove 4. An adjustment mechanism 6 is fixedly sleeved in the middle of the side of the hollow rod 2. The lower side of the adjustment mechanism 6 abuts and is locked in place with the side of the support and fixing mechanism 5.

[0031] A rectangular rod 7 is fixedly connected to the upper end of the hollow rod 2, and the lower side of the rectangular rod 7 is electrically connected to the support base 1. A storage groove 8 is provided on the side of the rectangular rod 7. A deflection plate 9 is hinged to the side of the storage groove 8. A compression spring 10 is fixedly connected to the side of the deflection plate 9. The end of the compression spring 10 away from the deflection plate 9 is fixedly connected to the side of the inner wall of the storage groove 8.

[0032] In this embodiment, as Figure 1 , Figure 3 , Figure 4 As shown, the support and fixing mechanism 5 includes an extrusion plate 51. One side of the extrusion plate 51 is hinged to the side of the inner wall of the groove 4. A rectangular frame 52 is movably sleeved on the side of the extrusion plate 51. A hinge rod 53 is hinged to the upper side of the rectangular frame 52, and the end of the hinge rod 53 away from the rectangular frame 52 is slidably connected to the side of the inner wall of the groove 4.

[0033] A limiting plate 54 overlaps the lower side of the extrusion plate 51, and the side of the limiting plate 54 is fixedly connected to the side of the supporting chassis 1. A tension spring 55 is fixedly connected to the side of the extrusion plate 51, and the end of the tension spring 55 away from the extrusion plate 51 is fixedly connected to the side of the rectangular frame 52.

[0034] In this embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a plug 11 is movably inserted into the bottom surface of the inner wall of the rectangular frame 52, and a compression spring 12 is fixedly connected to the top surface of the plug 11. The upper end of the compression spring 12 is fixedly connected to the top surface of the inner wall of the rectangular frame 52.

[0035] The side of the insert 11 has a slot 13.

[0036] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the control mechanism 6 includes a fixed bearing 61, which is fixedly sleeved on the middle part of the side of the hollow rod 2. An internally threaded tube 62 is fixedly sleeved on the side of the fixed bearing 61. Threaded sleeves 63 are rotatably connected to both the upper and lower sides of the inner wall of the internally threaded tube 62. The inner wall of the threaded sleeve 63 is slidably connected to the side of the hollow rod 2 and the side of the reinforcing rib 3. The lower side of the inner wall of the lower threaded sleeve 63 is in contact with and locked to the side of the hinge rod 53.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, a conductive wire is fixedly connected to the lower side of the rectangular rod 7, and one end of the conductive wire is fixedly connected to the input end of the support chassis 1. The rectangular rod 7 and the support chassis 1 are connected through the conductive wire. This design can realize the safe and reliable grounding of some live equipment when it is supported, and avoid the risk of electric shock to construction workers from live equipment.

[0038] In this embodiment, as Figure 3 As shown, a plug is fixedly connected to the bottom surface of the support chassis 1, and the plug is conical in shape. The plug ensures the stability of the support chassis 1 on the ground.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, there are two threaded sleeves 63, and the threads on the sides of the two threaded sleeves 63 are in the same direction. When the user rotates the internal threaded tube 62, the two threaded sleeves 63 can be stably moved downwards simultaneously, facilitating the opening of the deflection plate 9. The overall connection remains firm, and the bearing area at the top of the device is greatly increased, enabling support for large-area panels. It can also suspend wires of various diameters, measuring wires, and other connecting wires. At the same time, sliding the rectangular frame 52 towards one side of the extrusion plate 51 increases the stability of the device in contact with the ground.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, the side of the internally threaded tube 62 is wrapped with an insulating rubber sleeve to prevent users from getting electric shock when they come into contact with the internally threaded tube 62.

[0041] The method of use and advantages of the present invention: The working process of the portable multi-functional support device for temporary outdoor power construction is as follows:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown: by moving the device to the designated location, the support base 1 is placed on the ground, and the stability of the support base 1 is increased by the insert block on its lower side. Then, by rotating the internal thread tube 62, the internal thread tube 62 rotates counterclockwise, causing the two threaded sleeves 63 to move down, thereby causing the upper threaded sleeve 63 to move down. Under the action of the return force of the compression spring 10, the deflection plate 9 unfolds to better maintain a firm connection.

[0043] When the lower threaded sleeve 63 moves down, it presses the hinge rod 53, causing one end of the hinge rod 53 to move down in the groove 4, causing the rectangular frame 52 and the extrusion plate 51 to deflect parallel to the ground. At the same time as the rectangular frame 52 deflects, it slides on the side of the extrusion plate 51, increasing the overall length of the extrusion plate 51 and the rectangular frame 52, thereby increasing the contact area between the device and the ground and ensuring the stability of the device fixed on the ground.

[0044] Furthermore, when the rectangular frame 52 slides on the side of the extrusion plate 51, it causes one side of the extrusion plate 51 to separate from the side of the slot 13. Under the action of the reset force of the compression spring 12, the insert 11 pops out from inside the rectangular frame 52 and is inserted into the soil at the designated position, further increasing the stability of the device fixed on the ground.

[0045] When the user moves the device, rotating the internal threaded tube 62 clockwise causes the two threaded sleeves 63 to move upwards simultaneously on the side of the hollow rod 2. The upward movement of the upper threaded sleeve 63 presses the side of the deflection plate 9, causing the deflection plate 9 to be locked inside the storage slot 8. When the lower threaded sleeve 63 moves downwards, the tension spring 55 causes the rectangular frame 52 to reset, causing the hinge rod 53 to deflect and reset. The rectangular frame 52 causes the pressing plate 51 to deflect and reset. When the rectangular frame 52 resets, the slot 13 abuts and locks against one side of the pressing plate 51, allowing the slot 13 to be stored inside the rectangular frame 52, making it easy to fold and store the device.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
