Description

Technical Field

[0001] The utility model relates to the field of electric power construction tools, in particular to a mobile cable trench spanning device. Background Art

[0002] In cable construction, workers need to frequently detour the cable trench to reach the work point due to work needs, and constantly move various equipment and materials during the work process. This frequent detour not only increases the labor intensity of workers, but also greatly reduces work efficiency.

[0003] In order to solve the above problems, a simple crossing board is often used on the cable trench. Although this method improves work efficiency to a certain extent, due to the simple structure and poor stability of the crossing board, once it collapses, it will cause serious squeezing and damage to the cables below, causing irreversible damage to the cables. In addition, simple crossing boards usually lack necessary protective measures and cannot effectively guarantee the safety of workers.

[0004] The above two methods cannot take into account both work efficiency and safety. Utility Model Content

[0005] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions, and provide a mobile cable trench crossing device, so as to take into account both work efficiency and safety. To this end, the utility model adopts the following technical solutions.

[0006] A mobile cable trench crossing device comprises a main support frame and an auxiliary support frame located above the main support frame; a pulley and a pulley locking mechanism are provided at the lower end of the main support frame; the auxiliary support frame is transversely fixed above the main support frame, and telescopic mechanisms are provided at both ends of the auxiliary support frame.

[0007] The main support frame, as the basic support structure of the entire device, can be made of high-strength metal materials to ensure its stability and durability. The lower end of the main support frame is provided with a pulley and a pulley locking mechanism, so that the device can be easily moved to different work locations and stably parked through the locking mechanism. The auxiliary support frame is laterally fixed above the main support frame to provide sufficient support area to ensure the safe passage of operators and equipment. Both ends of the auxiliary support frame are provided with a telescopic mechanism, which can be adjusted according to the size of cable trenches of different sizes, so as to flexibly adapt to cable trenches of different sizes, so that the device has a wide range of adaptability and can be used stably in various construction environments. By using the mobile cable trench crossing device of the present invention, operators can cross the cable trench safely and quickly, avoid the trouble of frequent detours and handling of equipment and materials, thereby improving work efficiency; at the same time, the stability and adaptability of the device also ensure the safety of cables and construction personnel, and reduce construction risks. The main support frame can straddle the cable and has sufficient strength to prevent the cables in the cable trench from being hit by heavy objects.

[0008] As a preferred technical means: the main support frame includes four columns, a lower connecting rod frame arranged at the lower part of the columns, and an upper connecting rod frame arranged at the upper part of the columns; the lower ends of the four columns are provided with the pulleys.

[0009] The four-column design makes the main support frame have strong support capacity and stability, which can effectively support the entire device and the auxiliary support frame above, as well as the passing workers and equipment. The setting of the lower connecting rod frame and the upper connecting rod frame further strengthens the overall stability of the main support frame, making the device less likely to shake or tilt when crossing the cable trench. Pulleys are set at the lower ends of the four columns so that the entire device can be easily moved on the ground. The setting of the pulley locking mechanism ensures that the device can be stably parked in the designated position when needed to prevent slippage or movement during the crossing operation. The design of the main support frame enables it to straddle the cable firmly, forming a protective barrier, ensuring that people and objects working on the device will not directly contact the cables below, thereby effectively preventing the risk of cables being hit by heavy objects, which is crucial to protecting the integrity and safety of the cables.

[0010] As a preferred technical means: the auxiliary support frame includes telescopic mechanisms located on both sides and a plurality of parallel connecting rods located between the two telescopic mechanisms; the connecting rods are fixedly connected to the telescopic mechanisms.

[0011] The telescopic mechanisms on both sides of the auxiliary support frame can be flexibly adjusted according to cable trenches of different sizes. Whether it is a wide or narrow cable trench, it can be adapted by adjusting the length of the telescopic mechanism, thereby ensuring that the device can stably cross the cable trench. Multiple parallel connecting rods are fixedly connected to the telescopic mechanism to form a stable support structure, so that the auxiliary support frame can remain stable when bearing weight, and is not prone to deformation or collapse, ensuring the safety of operators walking and working on the device.

[0012] As a preferred technical means: the telescopic mechanism includes a hollow rod, telescopic rods located on both sides of the hollow rod, a screw located at the end of the telescopic rod and a limiter for limiting the movement of the telescopic rod, the screw head is provided with a top larger than the screw diameter, the telescopic rod is matched with the hollow rod, so that the telescopic rod can move relative to the hollow rod.

[0013] The design of the telescopic mechanism allows the telescopic rod to move inside the hollow rod, so that the length can be adjusted as needed, so that the entire device can adapt to cable trenches of different widths, improving the scope of application and practicality of the device. Through the cooperation of the screw and the limiter, the movement of the telescopic rod is effectively restricted and fixed, ensuring that the telescopic mechanism can remain stable after adjusting the length, and is not prone to shaking or deformation, thereby ensuring the stability of the entire device during use. The adjustment process of the telescopic mechanism is relatively simple, and the length adjustment can be completed by operating the screw and the limiter. This design reduces the difficulty of operation and improves work efficiency. The large-area top design makes the contact area between the telescopic mechanism and the cable trench wall larger, thereby providing stronger support force. The enhanced stability ensures that the device is not easy to shake or tilt when crossing the cable trench, providing a more stable working platform for the operator. Due to the improved contact strength, the top of the telescopic mechanism can better fit the cable trench wall, reducing the safety hazards caused by the slippage of the device. The large top design enables the telescopic mechanism to better adapt to cable trench walls of different shapes and materials, whether they are flat or slightly uneven, ensuring stable contact between the device and the trench wall, improving the adaptability of the device. The large top design can disperse the pressure of the device on the cable trench wall, reducing wear or damage caused by excessive force on a single point, helping to extend the service life of the device and reduce maintenance costs.

[0014] As a preferred technical means: the cross-sectional outer dimensions of the telescopic rod are smaller than the inner cavity dimensions of the hollow rod, the hollow rod is provided with a positioning hole, the telescopic rod is provided with a plurality of connecting holes that can be opposite to the positioning hole, the telescopic rod is inserted into the inner cavity of the hollow rod, the positioning hole of the hollow rod is opposite to the connecting hole of the telescopic rod, the limit piece is screwed into the positioning hole and the connecting hole to realize the positioning of the hollow rod and the telescopic rod, and the length of the screw is adjusted so that the telescopic mechanism supports the cable trench wall.

[0015] The cross-sectional outer dimensions of the telescopic rod are smaller than the inner dimensions of the hollow rod, so that the telescopic rod can be smoothly inserted into the inner cavity of the hollow rod. Through the cooperation of the positioning hole and the connecting hole, the limiter can be accurately screwed in to achieve the positioning of the hollow rod and the telescopic rod, which not only ensures the stability of the telescopic mechanism after adjusting the length, but also enables the entire device to firmly support the cable trench wall to prevent shaking or displacement during operation. Since the telescopic rod can move in the hollow rod, and the overall length of the telescopic mechanism can be changed by adjusting the length of the screw, the device can adapt to cable trenches of different widths. The operator can flexibly adjust the length of the telescopic mechanism according to actual needs to adapt to various construction environments. The design of the positioning hole and the connecting hole makes the adjustment process of the telescopic mechanism simple and convenient. The operator only needs to insert the telescopic rod into the inner cavity of the hollow rod, and then screw the limiter into the corresponding positioning hole and the connecting hole to complete the fixation. No complicated tools or skills are required, which reduces the difficulty of operation and improves work efficiency. The combined design of the telescopic rod and the hollow rod makes the entire telescopic mechanism compact and takes up little space. At the same time, due to the precise matching of the positioning holes and the connection holes, as well as the fixing effect of the limiter, the telescopic mechanism can maintain high stability during use and is not prone to deformation or damage. Through the precise positioning and fixing of the telescopic mechanism, the device can firmly support the cable trench wall to prevent shaking or tilting during operation. This helps reduce the risk of safety accidents caused by unstable devices and ensures the safety of operators.

[0016] As a preferred technical means: a telescopic foot is provided under the column.

[0017] The design of the telescopic feet enables the main support frame to easily cope with uneven or tilted ground. By adjusting the height of the telescopic feet, the main support frame can be ensured to remain horizontal and stable on different terrains, thereby preventing shaking or tilting caused by uneven ground. The telescopic feet increase the contact area between the main support frame and the ground, thereby improving the stability of the entire device, reducing the shaking caused by external forces during operation, and providing a more stable working platform for operators. The telescopic feet can not only adjust the height to adapt to different terrains when needed, but also retract when not needed, which is convenient for the movement and transportation of the device. In addition, by adjusting the telescopic feet, the main support frame can be easily positioned accurately on the cable trench, improving work efficiency. The design of the telescopic feet helps prevent the main support frame from accidentally collapsing or slipping during operation, thereby ensuring the safety of operators. By adjusting the height of the telescopic feet, friction or collision between the device and the cable can also be avoided, further reducing safety risks. The telescopic feet usually have a large adjustment range and can adapt to cable trenches of different depths, so that the main support frame can perform well in different working environments, improving the flexibility and adaptability of the device. The telescopic foot can be composed of multiple rods, which can be connected or slid together to adjust the length and adapt to the requirements of different heights and terrains. Of course, in addition to manual operation, the telescopic foot can also be driven by electric drive, hydraulic drive, mechanical drive, etc.

[0018] As a preferred technical means: the main support frame and the auxiliary support frame are welded into a whole.

[0019] The main support frame and the auxiliary support frame are connected into a whole by welding, making the entire support structure more stable and able to withstand greater external forces and loads, ensuring safety and stability during the operation. Compared with other connection methods (such as bolt connection, snap connection, etc.), welding connection does not require additional assembly steps and fasteners, which greatly simplifies the installation process, saves installation time, reduces installation costs, and improves construction efficiency.

[0020] As a preferred technical means: a spanning plate is laid on the surface of the auxiliary support frame, and the spanning plate and the auxiliary support frame are fixedly connected by a connecting piece.

[0021] The laying of the spanning plate provides a stable and flat working platform for the operators, which can effectively prevent the risk of slipping or falling when working on cable trenches or other uneven terrains. It provides better working conditions and safety for the operators. The existence of the spanning plate enables the operators to move and place tools, equipment or materials more conveniently without worrying about the uneven or unstable ground, reducing obstacles and delays in the operation process and improving the overall operation efficiency. The spanning plate is fixedly connected to the auxiliary support frame through the connector, which not only enhances the overall structural stability of the support frame, but also effectively disperses and bears the external force and load during the operation. The design of the spanning plate can be adjusted and optimized according to actual needs to adapt to cable trenches of different widths and depths or other working environments. The flexibility and detachability of the connector also make it easier to transport, install and disassemble, and adapt to different operation requirements; since the spanning plate and the auxiliary support frame are fixedly connected by the connector, when the spanning plate needs to be maintained or replaced, it can be easily disassembled and reinstalled, reducing the maintenance cost and difficulty.

[0022] As a preferred technical means: the width of the main support frame is smaller than that of the auxiliary support frame.

[0023] The smaller width of the main support frame makes it easier to move in the cable trench. In some narrow cable trenches or working areas, the smaller width of the main support frame can make it easier to place and fix; so that the support frame can better adapt to various complex and restricted working environments, and improve the flexibility and convenience of operations.

[0024] Beneficial effects: By using the mobile cable trench crossing device of the present invention, workers can cross the cable trench safely and quickly, avoiding the trouble of frequent detours and carrying equipment and materials, thereby improving work efficiency; at the same time, the stability and adaptability of the device also ensure the safety of cables and construction workers, reducing construction risks. The main support frame can cross the cables and has sufficient strength to prevent the cables in the cable trench from being hit by heavy objects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0032] Embodiment 1:

[0033] like Figure 1 , 2 As shown in Figure 3, a mobile cable trench crossing device includes a main support frame 1 and an auxiliary support frame 2 located above the main support frame; a pulley 4 and a pulley 4 locking mechanism 5 are provided at the lower end of the main support frame 1; the auxiliary support frame 2 is transversely fixed above the main support frame 1, and telescopic mechanisms are provided at both ends of the auxiliary support frame 2.

[0034] The main support frame 1, as the basic support structure of the entire device, can be made of a high-strength metal material to ensure its stability and durability. The lower end of the main support frame 1 is provided with a pulley 4 and a pulley 4 locking mechanism 5, so that the device can be easily moved to different work locations and stably parked through the locking mechanism 5. The auxiliary support frame 2 is laterally fixed above the main support frame 1 to provide sufficient support area to ensure the safe passage of operators and equipment. Both ends of the auxiliary support frame 2 are provided with a telescopic mechanism, which can be adjusted according to the size of cable trenches of different sizes, so as to flexibly adapt to cable trenches of different sizes, so that the device has a wide range of adaptability and can be used stably in various construction environments. By using the mobile cable trench crossing device of the present invention, operators can safely and quickly cross the cable trench, avoid the trouble of frequent detours and handling of equipment and materials, thereby improving work efficiency; at the same time, the stability and adaptability of the device also ensure the safety of cables and construction personnel, and reduce construction risks. The main support frame 1 can straddle the cable and has sufficient strength to prevent the cable in the cable trench from being hit by heavy objects.

[0035] In this embodiment, the main support frame 1 is in the shape of a square frame, and the main support frame 1 includes four columns 101, a lower connecting rod frame 102 arranged at the lower part of the column 101, and an upper connecting rod frame 103 arranged at the upper part of the column 101; the pulley 4 is arranged at the lower end of the four columns 101. The design of the four columns 101 makes the main support frame 1 have strong supporting capacity and stability, and can effectively support the entire device and the auxiliary support frame 2 above, as well as the passing workers and equipment. The setting of the lower connecting rod frame 102 and the upper connecting rod frame 103 further strengthens the overall stability of the main support frame 1, so that the device is not easy to shake or tilt when crossing the cable trench. The pulley 4 is arranged at the lower end of the four columns 101, so that the whole device can be easily moved on the ground, and the setting of the pulley 4 locking mechanism 5 ensures that the device can be stably parked at the designated position when needed to prevent slippage or movement during the crossing operation. The design of the main support frame 1 enables it to straddle the cables firmly to form a protective barrier, ensuring that personnel and objects working on the device do not directly contact the cables below, thereby effectively preventing the risk of cables being damaged by heavy objects, which is crucial to protecting the integrity and safety of the cables.

[0036] The auxiliary support frame 2 includes telescopic mechanisms located on both sides and a plurality of parallel connecting rods 201 located between the two telescopic mechanisms; the connecting rods 201 are fixedly connected to the telescopic mechanisms.

[0037] The telescopic mechanisms on both sides of the auxiliary support frame 2 can be flexibly adjusted according to cable trenches of different sizes. Whether it is a wide or narrow cable trench, it can be adapted by adjusting the length of the telescopic mechanism, thereby ensuring that the device can stably cross the cable trench. Multiple parallel connecting rods 201 are fixedly connected to the telescopic mechanism to form a stable support structure, so that the auxiliary support frame 2 can remain stable when bearing weight, and is not prone to deformation or collapse, thereby ensuring the safety of operators walking and working on the device.

[0038] like Figure 4 As shown, to facilitate adjustment in the width direction, the telescopic mechanism includes a hollow rod 202, telescopic rods 203 located on both sides of the hollow rod 202, a screw rod 3 located at the end of the telescopic rod 203 and a limiter 204 for limiting the movement of the telescopic rod 203. The head of the screw rod 3 is provided with a top portion larger than the diameter of the screw rod 3. The telescopic rod 203 matches the hollow rod 202 so that the telescopic rod 203 can move relative to the hollow rod 202.

[0039] The design of the telescopic mechanism allows the telescopic rod 203 to move in the hollow rod 202, so that the length can be adjusted as needed, so that the entire device can adapt to cable trenches of different widths, thereby improving the scope of application and practicality of the device. Through the cooperation of the screw 3 and the limiter 204, the movement of the telescopic rod 203 is effectively restricted and fixed, ensuring that the telescopic mechanism can remain stable after adjusting the length, and is not prone to shaking or deformation, thereby ensuring the stability of the entire device during use. The adjustment process of the telescopic mechanism is relatively simple, and the length adjustment can be completed by operating the screw 3 and the limiter 204. This design reduces the difficulty of operation and improves work efficiency. The large-area top design makes the contact area between the telescopic mechanism and the cable trench wall larger, thereby providing a stronger supporting force, and the enhanced stability ensures that the device is not easy to shake or tilt when crossing the cable trench, providing a more stable working platform for the operator. Due to the improvement of contact strength, the top of the telescopic mechanism can better fit the cable trench wall, reducing the safety hazards caused by the slippage of the device. The large top design enables the telescopic mechanism to better adapt to cable trench walls of different shapes and materials, whether they are flat or slightly uneven, ensuring stable contact between the device and the trench wall, improving the adaptability of the device. The large top design can disperse the pressure of the device on the cable trench wall, reducing wear or damage caused by excessive force on a single point, helping to extend the service life of the device and reduce maintenance costs.

[0040] In order to improve the reliability of positioning, the cross-sectional outer dimensions of the telescopic rod 203 are smaller than the inner cavity dimensions of the hollow rod 202. The hollow rod 202 is provided with a positioning hole, and the telescopic rod 203 is provided with a plurality of connecting holes that can be opposite to the positioning hole. The telescopic rod 203 is inserted into the inner cavity of the hollow rod 202, and the positioning hole of the hollow rod 202 is opposite to the connecting hole of the telescopic rod 203. The limiting member 204 is screwed into the positioning hole and the connecting hole to realize the positioning of the hollow rod 202 and the telescopic rod 203, and the length of the screw rod 3 is adjusted so that the telescopic mechanism can support the cable trench wall.

[0041] The cross-sectional outer dimensions of the telescopic rod 203 are smaller than the inner cavity dimensions of the hollow rod 202, so that the telescopic rod 203 can be smoothly inserted into the inner cavity of the hollow rod 202. Through the cooperation of the positioning hole and the connecting hole, the stopper 204 can be accurately screwed in to realize the positioning of the hollow rod 202 and the telescopic rod 203, which not only ensures the stability of the telescopic mechanism after adjusting the length, but also enables the entire device to firmly support the cable trench wall to prevent shaking or displacement during operation. Since the telescopic rod 203 can move in the hollow rod 202, and the overall length of the telescopic mechanism can be changed by adjusting the length of the screw 3, the device can adapt to cable trenches of different widths, and the operator can flexibly adjust the length of the telescopic mechanism according to actual needs to adapt to various construction environments. The design of the positioning hole and the connecting hole makes the adjustment process of the telescopic mechanism simple and convenient. The operator only needs to insert the telescopic rod 203 into the inner cavity of the hollow rod 202, and then screw the stopper 204 into the corresponding positioning hole and the connecting hole to complete the fixation, without the need for complex tools or skills, reducing the difficulty of operation and improving work efficiency. The combined design of the telescopic rod 203 and the hollow rod 202 makes the entire telescopic mechanism compact and occupies little space. At the same time, due to the precise matching of the positioning hole and the connecting hole, and the fixing effect of the limiter 204, the telescopic mechanism can maintain a high stability during use and is not prone to deformation or damage. Through the precise positioning and fixing of the telescopic mechanism, the device can firmly support the cable trench wall to prevent shaking or tilting during operation. This helps to reduce the risk of safety accidents caused by unstable devices and ensure the safety of operators.

[0042] In order to improve the reliability of the connection, the main support frame 1 and the auxiliary support frame 2 are welded into a whole.

[0043] The main support frame 1 and the auxiliary support frame 2 are connected into a whole by welding, making the entire support structure more stable and able to withstand greater external forces and loads, ensuring safety and stability during the operation. Compared with other connection methods such as bolt connection and snap connection, welding connection does not require additional assembly steps and fasteners, greatly simplifying the installation process, saving installation time, reducing installation costs, and improving construction efficiency.

[0044] For easy movement, the width of the main support frame 1 is smaller than that of the auxiliary support frame 2. The main support frame 1 with a smaller width is convenient for movement in the cable trench. In some narrow cable trenches or working areas, the smaller width of the main support frame 1 can make it easier to place and fix; so that the support frame can better adapt to various complex and restricted working environments, and improve the flexibility and convenience of operation.

[0045] Embodiment 2:

[0046] The same points as the first embodiment will not be described in detail, except that, in this embodiment, a telescopic foot is provided under the column 101 .

[0047] The design of the telescopic foot enables the main support frame 1 to easily cope with uneven or tilted ground. By adjusting the height of the telescopic foot, it can ensure that the main support frame 1 can maintain horizontal stability on different terrains, thereby preventing shaking or tilting caused by uneven ground. The telescopic foot increases the contact area between the main support frame 1 and the ground, thereby improving the stability of the entire device, reducing the shaking caused by external forces during operation, and providing a more stable working platform for operators. The telescopic foot can not only adjust the height when needed to adapt to different terrains, but also shrink when not needed, which is convenient for the movement and transportation of the device. In addition, by adjusting the telescopic foot, the main support frame 1 can be easily positioned accurately on the cable trench, improving the working efficiency. The design of the telescopic foot helps to prevent the main support frame 1 from accidentally collapsing or slipping during operation, thereby ensuring the safety of the operators. By adjusting the height of the telescopic foot, friction or collision between the device and the cable can also be avoided, further reducing safety risks. The telescopic foot usually has a large adjustment range and can adapt to cable trenches of different depths, so that the main support frame 1 can perform well in different working environments, improving the flexibility and adaptability of the device. The telescopic foot can be composed of multiple rods, which can be connected or slid together to adjust the length and adapt to the requirements of different heights and terrains. Of course, in addition to manual operation, the telescopic foot can also be driven by electric drive, hydraulic drive, mechanical drive, etc.

[0048] Manual drive: This is the simplest and most direct drive method. The telescopic leg is extended and retracted by manually rotating or pushing and pulling the operating rod or handle on the telescopic leg. This drive method does not require electricity or other external energy, but it requires manual force during operation, and the adjustment accuracy and speed may be limited.

[0049] Electric drive: The motor is used as the power source to drive the mechanical mechanism inside the telescopic leg to perform telescopic movement. The electric drive method has the characteristics of fast response speed and high precision, and can realize automatic control. It is usually connected to the control system through wires or wireless signals, which is convenient for remote operation and monitoring.

[0050] Hydraulic drive: Using liquid pressure as the power source, the telescopic legs are driven to extend and retract through a hydraulic cylinder or hydraulic motor. The hydraulic drive method has the characteristics of large driving force and good stability, and is suitable for occasions that need to withstand large loads. It usually uses hydraulic oil as the working medium and realizes precise adjustment of the telescopic action through a hydraulic control system.

[0051] Mechanical drive: The power of the power source such as the motor or engine is transmitted to the telescopic foot through mechanical transmission mechanisms such as gears, chains, belts, etc. to achieve telescopic action. The mechanical drive method has a relatively simple structure and high reliability.

[0052] Embodiment three:

[0053] like Figure 5 As shown, the same points as the first embodiment are not repeated here. The difference is that, in order to provide a stable and flat working platform, a crossing plate 6 is laid on the surface of the auxiliary support frame 2, and the crossing plate 6 is fixedly connected to the auxiliary support frame 2 by a connecting piece.

[0054] To prevent the stopper 204 from affecting the installation of the spanning plate 6, the stopper can be arranged on the side or bottom of the auxiliary support frame 2, and the stopper 204 can be a latch, a screw, etc. Of course, for the reliability of the work, the stopper 204 can also be inserted into the telescopic mechanism from above, in which case the stopper 204 can be a screw with high strength and not very obvious protrusion, etc., and an auxiliary support frame 2 with a suitable length can also be used to avoid the stopper 204 from being pressed during transportation.

[0055] The spanning plate 6 can effectively prevent the risk of slipping or falling when the operator is working on the cable trench or other uneven terrain. It provides better working conditions and safety for the operators. The existence of the spanning plate 6 enables the operators to move and place tools, equipment or materials more conveniently without worrying about the problem of uneven or unstable ground, reducing obstacles and delays in the operation process and improving the overall operation efficiency. The spanning plate 6 is fixedly connected to the auxiliary support frame 2 by a connector, which not only enhances the overall structural stability of the support frame, but also effectively disperses and withstands the external force and load during the operation. The design of the spanning plate 6 can be adjusted and optimized according to actual needs to adapt to cable trenches or other working environments of different widths and depths. The flexibility and detachability of the connector also make it easier to transport, install and disassemble, and adapt to different operation requirements; since the spanning plate 6 is fixedly connected to the auxiliary support frame 2 by a connector, it can be easily disassembled and reinstalled when the spanning plate 6 needs to be maintained or replaced, reducing the maintenance cost and difficulty.
