Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a large-scale indoor equipment transfer device. Background Art

[0002] Power facilities and equipment are crucial in the power industry, involving power transmission and control. When installing and using some equipment and facilities, heavy-duty transport and lifting tools, such as cranes and electric forklifts, are required. Sometimes, heavy-duty handling tools cannot reach the site due to environmental and space limitations. Therefore, in these special cases, it becomes very difficult to move these large power equipment and facilities, requiring a lot of manpower or the use of simple tools to operate the equipment. During operation, due to inadequate protective measures, people may be injured or even their lives may be in danger. There are also more complicated situations where the environment requires transportation and lifting. For example, there are steps inside and outside the door of the distribution room, and the existing manual equipment cannot meet these requirements. The lifting platform cannot be connected to the door, and the steps block the connection between the equipment and the door.

[0003] The roller transport method currently used in on-site construction is to place large equipment such as transformers and ring main units on a support rack, and place a certain number of rollers under the rack. The rollers are laid on the walkway and transported by manpower. Although the roller transport method is simple, there are two problems. First, the labor intensity is high during transportation and more manpower is required; second, there are steps in front of the doors of most distribution rooms. When moving transformers, ring main units and other equipment to the distribution room door, a ramp walkway must be set up and then transported by manpower, which poses a serious safety hazard. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a large-scale indoor equipment transfer device to improve the transfer efficiency and ensure the personal safety of construction workers.

[0005] In order to solve the above technical problems, the present invention provides an indoor large equipment transfer device, comprising:

[0006] Support base;

[0007] An inverted U-shaped column, wherein two columns of the inverted U-shaped column are fixedly connected to the support base; the two columns are C-shaped steel, and column grooves are formed on the surface;

[0008] A hydraulic cylinder is arranged on the supporting base;

[0009] A hydraulic cylinder telescopic rod, the bottom end of which is connected to the hydraulic cylinder;

[0010] A sprocket transverse axis, the sprocket transverse axis is arranged between the two columns, and the sprocket transverse axis is in contact with the top end of the telescopic rod of the hydraulic cylinder;

[0011] Two sprockets are arranged on the sprocket transverse axis;

[0012] Two chains, the two chains are respectively nested on the two sprockets;

[0013] Universal wheels, arranged at the bottom of the support base through wheel brackets;

[0014] A load-bearing platform, used to bear large equipment, one side of the load-bearing platform is connected to one end of the two chains, and the other ends of the two chains are connected to the support base;

[0015] Two sets of lifting wheels are arranged on the bearing platform and respectively embedded in the column grooves of the two columns, and can move up and down along the column grooves of the two columns; and

[0016] Two movable support mechanisms are respectively arranged at two ends of the other side of the carrying platform, and are used to automatically adjust according to the lifting action of the carrying platform to support the carrying platform;

[0017] When the hydraulic cylinder is operated, the telescopic rod of the hydraulic cylinder is pushed to extend or retract upward, driving the sprocket horizontal axis to rotate counterclockwise or clockwise, driving the two chains to move, and the carrying platform is driven to rise and fall through the two chains, and the two sets of lifting wheels guide the carrying platform to rise and fall stably.

[0018] Furthermore, it also includes two handrails, one end of the two handrails is connected to the upper part of the two columns respectively, and the other end is connected to the two sides of the top of the support base.

[0019] Furthermore, the bearing platform includes two steel plates arranged vertically in parallel, a plurality of square tubes, a plurality of rollers and a supporting crossbar. The two steel plates are connected by brackets located at both ends of the two steel plates. One end of the plurality of square tubes and the plurality of rollers is connected to a steel plate located below, and the other end is connected to the supporting crossbar.

[0020] Furthermore, an operating portion is provided on the hydraulic cylinder, and the operating portion is used for an operator to step on to operate the hydraulic cylinder.

[0021] Furthermore, the movable support mechanism includes a connecting movable arm, one end of which is connected to the supporting crossarm through a fixed shaft, and the other end is provided with a wheel fixing platform, and wheels are installed on the wheel fixing platform. The movable support mechanism is used to provide stable support and facilitate movement.

[0022] Furthermore, four wheels are mounted on each of the wheel fixing platforms.

[0023] The indoor large equipment transfer device of the present invention has the following beneficial effects:

[0024] (1) The hydraulic cylinder drive reduces manpower input and improves handling efficiency. The traditional roller bar handling method requires a lot of manpower, while the present invention only requires operating the hydraulic cylinder to achieve the lifting and handling of the equipment.

[0025] (2) The design of the present invention reduces the potential safety hazards caused by improper manual handling. Through the hydraulic system and stable lifting wheels, the stability of the equipment during the handling process can be ensured, reducing the risk of accidents.

[0026] (3) The device's universal wheels and lifting wheels enable it to adapt to different indoor environments, especially in places with steps or limited space, which can effectively solve the problem of equipment transportation.

[0027] (4) The movable support mechanism can automatically adjust according to the lifting and lowering action of the load-bearing platform, ensuring the balance and safety of the equipment during transportation.

[0028] The present invention has broad application prospects, especially in the field of installation and maintenance of power facilities and equipment, and can greatly improve work efficiency, reduce labor intensity, and provide a safe and efficient handling solution for the power industry.

[0039] An inverted U-shaped column 2, wherein two columns of the inverted U-shaped column 2 are fixedly connected to the support base 1; the two columns are C-shaped steel, and column grooves are formed on the surface; specifically, the inverted U-shaped column 2 is a vertical support structure of the device, and its two columns are fixedly connected to the support base 1 to form a stable frame; the column is made of C-shaped steel, which is both light and strong, and the column grooves formed on the surface are used to embed the lifting wheels 9, so that the bearing platform can move up and down smoothly along the column grooves;

[0040] The hydraulic cylinder 3 is arranged on the support base 1; specifically, the hydraulic cylinder 3 is a power source, which is arranged on the support base 1 and generates a push and pull force through hydraulic action; the selection of the hydraulic cylinder 3 needs to be determined according to the weight of the required handling equipment to ensure that there is sufficient power to complete the handling task;

[0041] The hydraulic cylinder telescopic rod 3 has a bottom end connected to the hydraulic cylinder 3; specifically, the hydraulic cylinder telescopic rod 3 is connected to the hydraulic cylinder 3, and its top end is in contact with the sprocket horizontal axis 5; when the hydraulic cylinder 3 is working, the extension or retraction of the telescopic rod will be directly converted into the rotational movement of the sprocket horizontal axis 5;

[0042] The sprocket transverse axis 5 is arranged between the two columns, and the sprocket transverse axis 5 contacts the top of the hydraulic cylinder telescopic rod 3; the sprocket transverse axis 5 is arranged between the two columns, and two sprockets 6 are fixed at both ends; the function of the sprocket transverse axis 5 is to transmit the push and pull force of the hydraulic cylinder telescopic rod 3, and drive the chain 7 by rotating the sprocket 6;

[0043] Two sprockets 6 are arranged on the sprocket transverse axis 5; the sprockets 6 are fixed on the sprocket transverse axis 5 and work in conjunction with the chain 7; the diameter and number of teeth of the sprockets 6 will affect the lifting speed and stability of the load-bearing platform;

[0044] Two chains 7, the two chains 7 are respectively nested on the two sprocket wheels 6; the chain 7 is nested on the sprocket wheel 6, one end of the chain 7 is connected to the bearing platform, and the other end is connected to the support base 1; the chain 7 moves under the drive of the sprocket wheel 6, thereby driving the lifting of the bearing platform;

[0045] Universal wheels 8 are arranged at the bottom of the support base 1 through wheel brackets; specifically, the universal wheels 8 are arranged at the bottom of the support base 1 through wheel brackets, so that the entire device can be flexibly moved in an indoor environment; the design of the universal wheels 8 allows the device to remain stable on uneven ground;

[0046] The load-bearing platform is used to carry large equipment, one side of the load-bearing platform is connected to one end of the two chains 7, and the other end of the two chains 7 is connected to the support base 1; specifically, the load-bearing platform is used to place large equipment, and one side of the load-bearing platform is connected to the chain 7; the area and structural design of the platform must meet the size and weight requirements of the equipment to ensure stability during transportation;

[0047] Two sets of lifting wheels 9 are arranged on the bearing platform and respectively embedded in the column grooves of the two columns, and can move up and down along the column grooves of the two columns; specifically, the lifting wheels 9 are arranged on the bearing platform and respectively embedded in the column grooves of the two columns; the function of the lifting wheels 9 is to guide the bearing platform to stably rise and fall along the column grooves to reduce friction and bumps;

[0048] and, two movable support mechanisms, respectively disposed at the two ends of the other side of the carrying platform, for automatically adjusting to support the carrying platform according to the lifting action of the carrying platform; specifically, the movable support mechanisms are located at the two ends of the other side of the carrying platform, and they can automatically extend or retract according to the lifting action of the carrying platform to keep the platform in a horizontal state; this helps to maintain balance during the handling of the equipment, especially when the carrying platform reaches a certain height;

[0049] When the hydraulic cylinder 3 is operated, the hydraulic cylinder telescopic rod 3 is pushed to extend or retract upward, driving the sprocket horizontal axis 5 to rotate counterclockwise or clockwise, driving the two chains 7 to move, and the carrying platform is driven to rise and fall through the two chains 7, and the two sets of lifting wheels 9 guide the carrying platform to rise and fall stably.

[0050] Specifically, place the large equipment stably on the load-bearing platform, and ensure that the center of gravity of the equipment is located at the center of the platform to maintain balance during transportation; operate the hydraulic cylinder 3 to push the hydraulic cylinder telescopic rod 3 to extend upward; the extension of the telescopic rod will push the sprocket horizontal axis 5 to rotate counterclockwise; the rotation of the sprocket horizontal axis 5 drives the sprocket 6 to rotate, and then transmits power through the chain 7, so that the chain 7 moves along the sprocket 6; as the chain 7 moves, the load-bearing platform begins to rise; the lifting wheel 9 moves up and down along the column groove rail to guide the load-bearing platform to rise and fall stably; at the same time, the movable support mechanism automatically extends or retracts according to the lifting action of the load-bearing platform to maintain the load-bearing platform horizontal state; when the carrying platform rises to the required height, the entire device can be moved by operating the universal wheel 8 to transport the equipment to the designated location; after arriving at the destination, the hydraulic cylinder 3 is operated to retract the hydraulic cylinder telescopic rod 3; the retraction of the telescopic rod will drive the sprocket horizontal axis 5 to rotate in the clockwise direction; the rotation of the sprocket horizontal axis 5 will drive the chain 7 to move again, but this time it will lower the carrying platform; the lifting wheel 9 continues to move along the column groove to ensure that the carrying platform descends smoothly; the movable support mechanism is adjusted synchronously to support the carrying platform and prevent it from tilting; when the carrying platform is lowered to the ground or a suitable height, the large equipment can be safely unloaded from the carrying platform.

[0051] The device of this embodiment realizes efficient and safe transportation of large equipment in indoor environment. The combination of hydraulic drive system and chain 7 transmission mechanism ensures the stability and controllability of the transportation process, while the design of lifting wheel 9 and movable support mechanism further improves the safety and stability of the transportation process.

[0052] Furthermore, both ends of the sprocket shaft 5 can be movably mounted on two columns by bearings, so that the sprocket shaft 5 can rotate; the hydraulic cylinder 3 can be composed of a cylinder body, a telescopic piston rod, and a hydraulic oil circuit. When the hydraulic oil is pumped into a chamber of the hydraulic cylinder 3, it will generate pressure on the piston, pushing the piston to move, thereby causing the piston rod to retract; the top end of the hydraulic cylinder telescopic rod 3 can be connected to a mechanical transmission device, such as a crank, a gear or directly connected to the sprocket shaft 5. When the hydraulic oil is pumped into the pushing chamber of the hydraulic cylinder 3, the piston is subjected to pressure and begins to move toward the other end of the cylinder body; since the piston rod and the piston are fixedly connected, the movement of the piston causes the piston rod to extend outward (i.e., the telescopic rod is extended); the top end of the piston rod is connected to the sprocket shaft One end of the shaft 5, so the extension of the piston rod will directly push the sprocket horizontal axis 5 to rotate in one direction (assuming it is counterclockwise); the other end of the sprocket horizontal axis 5 is usually connected to another sprocket 6 or fixed to a supporting structure to form a fixed rotating axis; when the sprocket horizontal axis 5 rotates, the sprocket 6 fixed on the horizontal axis will also rotate accordingly; the chain 7 bypasses these two sprockets 6, so the rotation of the sprocket 6 will drive the chain 7 to move, thereby realizing the lifting and lowering of the load-bearing platform; when the load-bearing platform needs to be lowered, hydraulic oil will be pumped into the other chamber of the hydraulic cylinder 3, pushing the piston to move in the opposite direction, causing the piston rod to retract; the retraction of the piston rod will pull the sprocket horizontal axis 5 to rotate in the opposite direction (assuming it is clockwise), thereby driving the chain 7 to move in the opposite direction, causing the load-bearing platform to descend.

[0053] Furthermore, in order to facilitate the rotation of the sprocket axis 5 by the telescopic rod, the surfaces of the telescopic rod and the sprocket axis 5 are meshed. For example, keyways can be provided on the telescopic rod and the sprocket axis 5, and the meshing of the two is achieved through keys, thereby transmitting rotational motion.

[0054] Furthermore, two handrails 10 are included, one end of the two handrails 10 is connected to the upper part of the two columns respectively, and the other end is connected to the two sides of the top of the support base 1.

[0055] Specifically, the operator can use the handrail 10 to push or pull the entire device to move large equipment in an indoor environment. When the device direction needs to be changed, the operator can achieve steering by holding the handrail 10 on different sides.

[0056] Furthermore, the bearing platform includes two steel plates 11 arranged vertically in parallel, a plurality of square tubes 12, a plurality of rollers 13 and a supporting crossbar 14. The two steel plates 11 are connected by brackets located at both ends of the two steel plates 11. One end of the plurality of square tubes 12 and the plurality of rollers 13 is connected to a steel plate 11 located below, and the other end is connected to the supporting crossbar 14.

[0057] Specifically, the upper and lower steel plates 11 can increase the rigidity of the platform and prevent bending or deformation. The brackets located at both ends of the two steel plates 11 are used to connect the upper and lower steel plates 11 to ensure fixation and stability between them. The brackets may be connected to the steel plates 11 by welding, bolts or other fasteners.

[0058] The square tube 12 is arranged below the steel plate 11 to increase the overall strength and stability of the platform. The material of the square tube 12 is usually metal, such as steel or aluminum alloy, to provide sufficient supporting force. One end of the square tube 12 is connected to the steel plate 11 below and can be fixed by welding or bolts.

[0059] The roller bar 13 is used to reduce the friction of the platform when it moves, so that large equipment can be pushed more easily. The roller bar 13 is usually made of hard material, such as steel or plastic, and is equipped with bearings to achieve smooth rolling. One end of the roller bar 13 is connected to the lower steel plate 11, and the other end is connected to the supporting cross arm 14.

[0060] The supporting cross arm 14 is located below the platform and is used to fix the other end of the roller bar 13 and support the weight of the entire platform. The design of the supporting cross arm 14 needs to ensure sufficient strength and stability to prevent the platform from sinking or deforming when carrying heavy objects.

[0061] Through the steel plates 11 and square tubes 12 arranged in parallel up and down, the load-bearing platform can evenly distribute the weight of the equipment and reduce the pressure on a single point; the design of the roller 13 allows the load-bearing platform to be relatively easy to move on the indoor floor, and even when carrying heavy objects, the structure supporting the cross arm 14 and the square tube 12 improves the overall stability of the platform and reduces the swaying or tilting that may occur during the transportation process. Through such a design, the load-bearing platform can not only safely carry large equipment, but also can be conveniently coordinated with other transfer device components to realize the indoor transfer of equipment.

[0062] Furthermore, an operating part is provided on the hydraulic cylinder 3, and the operating part is designed as a pedal for an operator to step on to operate the hydraulic cylinder 3. The operator can control the extension and retraction of the hydraulic cylinder 3 and further control the lifting or movement of the carrying platform by stepping on or releasing the operating part.

[0063] Furthermore, the movable support mechanism includes a connecting movable arm 15, one end of which is connected to the supporting crossbar 14 through a fixed shaft, and the other end is provided with a wheel fixing platform 16, on which wheels are installed. The movable support mechanism is used to provide stable support and facilitate movement.

[0064] Specifically, the design of the movable support mechanism enables it to automatically extend or retract according to the lifting action of the load-bearing platform to maintain the horizontal state of the platform. The connecting movable arm 15 in the movable support mechanism can be regarded as a lever, one end of which is fixed to the supporting crossbar 14 and the other end is equipped with a wheel. When the load-bearing platform is lifted or lowered, the position of the supporting crossbar 14 changes. Through the principle of lever, the connecting movable arm 15 will extend or retract accordingly. The movable support mechanism adopts a scissor-type structure, which can keep the wheels on both sides moving in parallel when the platform is lifted or lowered, thereby maintaining the horizontal state of the platform. The movable support mechanism can use a spring as a power source. When the platform is lifted or lowered, the expansion and contraction of the spring will push or pull the support mechanism to automatically extend or retract.

[0065] Furthermore, four wheels 17 are mounted on each of the wheel fixing platforms 16 .

[0066] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
