Description

Technical Field

[0001] The invention relates to the technical field of crossing frames, and in particular to a scissor-type lifting crossing frame. Background Art

[0002] In the process of transmission line construction, various obstacles such as roads, railways, communication and broadcasting lines, and power lines are often encountered. In order to prevent the conductors from being damaged and not affecting the safe operation of the objects being crossed, crossing frames will be set up at these crossovers before laying out the lines to allow the conductors to pass safely and smoothly. At present, the corresponding common crossing methods for various types of crossing objects include bamboo crossing frames, steel pipe crossing frames, portal frames, crane-lifted beams / wire turning frames, suspension bridge sealing nets, etc. However, the above-mentioned various types of crossing frames are limited in use due to their narrow scope of application and difficulty in construction.

[0003] Even though other types of crossing frames have been proposed in the prior art, they still have problems such as a narrow scope of application. For example, the patent document with the authorization announcement number CN112249964B discloses a lifting crossing frame for power transmission line construction, which comprises a first fixed plate, a conductor clamp, a telescopic connection, a first lifting mechanism, a second lifting mechanism and a flipping mechanism; the telescopic connection is installed at the bottom of the first fixed plate; the conductor clamp is installed on the first fixed plate; the first lifting mechanism is vertically installed on the transport frame and is used to drive the first fixed plate to rise and fall; the second lifting mechanism is hingedly arranged directly below the first fixed plate, and the lifting stroke of the second lifting mechanism for driving the first fixed plate is greater than the lifting stroke of the first lifting mechanism for driving the first fixed plate to rise and fall; the flipping mechanism is connected to the second lifting mechanism and is used to drive the second lifting mechanism to flip around the hinge of the second lifting mechanism, so that the second lifting mechanism flips to a vertical state to drive the first fixed plate to rise and fall.

[0004] The above-mentioned lifting and crossing frame is an integrated overall structure, and the cables to be crossed in the prior art are also used as an integral transmission line. Therefore, when the lifting and crossing frame is used to install the cables to be crossed, it is necessary to repeatedly adjust the relative positions of the lifting and crossing frame as a whole and the cables to be crossed as a whole so that the lifting and crossing frame can be installed in a better lifting position. However, this process is time-consuming and delays the construction progress. If the environment of the cables to be crossed is bad, the lifting and crossing frame may not be able to move around the cables to be crossed, that is, the lifting and crossing frame has the defect of a narrow adaptability range.

[0005] Taking a conventional place (such as a flat road) as an example, after the relative position of the lifting spanning frame and the spanned cable is adjusted, the second fixing plate is lifted by the upward lifting of the scissor bracket and the first telescopic pusher until the height of the second fixing plate is greater than the height of the spanned cable. This state can be Figure 1In the figure, 101 represents a lifting and crossing frame of the prior art, 102 represents a crossed cable located below, and 103 represents a running wire located above. Generally, in order to ensure that the running wire located above always maintains a safe distance from the crossed cable located below, the lifting and crossing frame is generally provided in two groups, and the two groups of lifting and crossing frames are respectively arranged on both sides of the crossed cable, such as Figure 1 As shown, the second fixing plates on the two sets of lifting and crossing frames will lift the running wires to a corresponding height, making it easier for the running wires to pass over the crossed cables.

[0006] However, the above-mentioned lifting spanning frame generally needs to be set up in at least two groups during use, which not only increases the construction cost, but also the two groups of lifting spanning frames work relatively independently, and the two groups do not interfere with each other. When working, the two groups of lifting spanning frames will lift the corresponding positions of the running wires respectively, and there is no connection between the two groups. For example, the patent document with patent publication number CN108718058A discloses a self-lifting and rotatable cantilever spanning frame, which is also set up in at least two groups and distributed on both sides of the spanned cable when in use, and there is no connection between the two groups of spanning frames.

[0007] In summary, under the above-mentioned span structure, if the wire feeding speed of the running wire is greater than the wire routing speed when passing through, this situation will cause the part of the running wire located between the two sets of lifting spans to become loose and droopy. If this situation is not intervened, in serious cases, this part of the running wire will touch the crossed cable, and an accident will occur. If, on the basis of the above-mentioned span structure, a connection is added between the two sets of spans, such as a protective net, since the protective net needs to be set above the crossed cable, and then after the two sets of spans are lifted to the corresponding height, it is necessary to manually climb to the corresponding height and tie the two ends of the protective net to the top of the two sets of spans respectively. This high-altitude operation not only requires professional lifting devices to lift the construction personnel, but also the high-altitude operation itself has certain risks.

[0008] To this end, we propose a scissor-type lifting and crossing frame to solve the above problems. Summary of the invention

[0013] As a further solution of the present invention: a second driving member is hingedly provided on the main arm, and a piston end of the second driving member is hingedly connected to the auxiliary arm, so that the auxiliary arm can rotate with its hinge point as the center and keep the auxiliary arm in a horizontal state.

[0014] As a further solution of the present invention: a ring is provided at the auxiliary arm of one group of crossing components, and a hook is provided at the auxiliary arm of the other group of crossing components. Both the ring and the hook can be adjusted to a horizontal state through a corresponding second driving member to achieve a buckled connection between the two.

[0015] As a further solution of the present invention: the main arm is provided with a transfer shaft for rotationally connecting with the top of the support frame, and the transfer shaft and the main arm are arranged in an L shape, and the support frame is provided with a first driving member, and the first driving member is used to drive the transfer shaft to rotate horizontally.

[0018] As a further solution of the present invention: the spanning assembly also includes a lifting member for driving the support frame to perform a lifting action.

[0019] As a further solution of the present invention: the lifting member is formed by a plurality of scissor-type lifting brackets stacked in a vertical direction, a foot pad is arranged at the bottom of the lowest scissor-type lifting bracket, and the support frame is arranged on the top of the highest scissor-type lifting bracket.

[0020] As a further solution of the present invention: the spanning assembly also includes a traction rope with one end connected to the scissor-type lifting bracket, and the other end of the traction rope is provided with a ground spike for being inserted into the ground.

[0021] Furthermore, the present invention also discloses a method for using a scissor-type lifting spanning frame, which comprises the following steps:

[0022] Step 1: Two groups of spanning components are respectively arranged on both sides of the spanned cable, and then the support frame is lifted to the corresponding height by using the lifting parts thereon, until the two swing arms arranged opposite to each other on the two groups of spanning components are located on the same horizontal plane, and the single barrier net composed of any two adjacent swing arms on the same spanning component is in the storage state;

[0023] Step 2: Use the second driving member to drive the auxiliary arm to rotate and adjust until the two auxiliary arms arranged opposite to each other on the two groups of spanning components are on the same horizontal plane, that is, the two single barrier nets arranged opposite to each other and in the storage state on the two groups of spanning components are on the same horizontal plane;

[0024] Step three: Use the first driving member to drive the swing arm to rotate horizontally, so that the single-body barrier net changes from the stored state to the deployed state. During this state change process, the two single-body barrier nets arranged relatively to each other on the two sets of spanning components will be connected by means of rings and hooks to realize the connection of the two single-body barrier nets and complete the connection of the two sets of spanning components.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Through the setting of two groups of spanning components, the two relatively single blocking nets in the two groups of spanning components can be arranged on both sides of the spanned cable respectively, and the two single blocking nets can be transformed from the initial storage state to the unfolded state during work, and the two single blocking nets can be well buckled, so that the two groups of spanning components are built into a stable whole, which plays a good lifting and protection role for the running wire;

[0027] 2. By setting the swing arm as the main arm and the auxiliary arm, before the single-body barrier net changes from the stowed state to the deployed state, the position of the auxiliary arm can be adjusted and rotated by using the second driving member, so that the two single-body barrier nets located on both sides of the cable to be crossed can be arranged in the same plane. In the subsequent process of the single-body barrier net changing from the stowed state to the deployed state, the auxiliary arms of the two single-body barrier nets can be accurately buckled;

[0028] 3. Through the setting of the hook and the ring, the hook and the ring are respectively set on the auxiliary arms on the two groups of spanning components. When the single-body barrier net is transformed from the storage state to the unfolded state, the hook and the ring are arranged in the same plane, and the hook can be inserted into the ring to achieve buckling, thereby completing the connection between the two single-body barrier nets, and the connection is convenient;

[0029] 4. Through the setting of the scissor-type lifting bracket, this type of bracket can be adapted to different places, not limited to flat ground and other places, and this bracket can also be used to make preliminary rough adjustments to the single barrier net to ensure that the heights of the two single barrier nets on both sides of the crossed cable remain basically consistent;

[0030] 5. Through the setting of the second driving member, the positions of the two opposite monomer barrier nets on both sides of the crossed cable are adjusted by using the second driving member. This is a fine adjustment, which is intended to ensure that the two opposite monomer barrier nets on both sides of the crossed cable are arranged in the same plane, so as to realize the subsequent buckling of the two sets of monomer barrier nets;

[0031] 6. By setting the inclined rods, the two inclined rods are arranged in an inverted eight-shaped shape in the vertical direction, so that the running wire can be restricted within the area formed by the two inclined rods, preventing the running wire from being dislodged from the crossing component during its movement.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] like Figure 2-Figure 8 As shown, a scissor-type lifting and crossing frame is used to be arranged around the cable 102 to be crossed. According to the state after its arrangement, the lifting and crossing frame includes two groups of crossing components, which are arranged on both sides of the cable 102 to be crossed, and the working heights of the two groups of crossing components are higher than the cable 102 to be crossed. The two groups of crossing components can cooperate to a certain extent, so that the two groups of crossing components cooperate to lift the running wire 103 to a certain height to avoid contact with the cable 102 to be crossed, and there is a certain connection between the two groups of crossing components to ensure the stability of the two groups of crossing components when working. This working state can be controlled by Figure 2 To express.

[0045] The following is an introduction to the spanning component structure:

[0046] (1) The spanning assembly includes at least two support frames 1 that can be lifted and lowered in the vertical direction. Figure 2 The figure shows a situation where four support frames 1 are provided, a swing arm 2 is rotatably provided on the top of the support frame 1, and a plurality of blocking ropes 3 are provided between any two adjacent swing arms 2 that can swing in the horizontal direction, so that the two adjacent swing arms 2 and the plurality of blocking ropes 3 together form a single blocking net; Figure 2 Taking the arrangement of four support frames 1 as an example, a total of four swing arms 2 are arranged on the four support frames 1, and thus there are four groups of single-body barrier nets.

[0047] (2) The component that drives the support frame 1 to move up and down can be composed of a plurality of scissor-type lifting brackets 13 stacked in the vertical direction, wherein a foot pad 14 is provided at the bottom of the lowest scissor-type lifting bracket 13, and the support frame 1 is provided on the top of the highest scissor-type lifting bracket 13.

[0048] The following is an introduction to the storage status and working status of the spanning component working status:

[0049] (1) When the two single-body barrier nets located on both sides of the crossed cable 102 are in the storage state, the two single-body barrier nets are arranged in an eight-shaped shape in the horizontal direction. This state can be Figure 3 To represent, this state can be expressed as: the scissor-type lifting bracket 13 lifts the support frame 1 to the corresponding position, and the swing arm 2 on the support frame 1 is in an unfolded state.

[0050] (2) When the two single-body barrier nets on both sides of the crossed cable 102 are in the unfolded state, the two single-body barrier nets are in the same plane, and the proximal ends of the two are in the buckled state. This state can be Figure 2 To represent, this state can be expressed as: Figure 3 In the shown state, the swing arm 2 is automatically driven to rotate, so that the two relatively arranged swing arms 2 on both sides of the crossed cable 102 rotate at the same time, and the ends of the two swing arms 2 close to each other are buckled together, thereby making the two relatively single barrier nets on the two groups of crossing components buckled, that is, the working states of the two groups of crossing components are connected, ensuring the stability of the two groups of crossing components when working.

[0051] like Figure 5 and Figure 8 As shown, for the arrangement of the above-mentioned middle swing arm 2 structure, the swing arm 2 includes a main arm 201 horizontally rotatably arranged on the top of the support frame 1 and a secondary arm 202 hingedly arranged on the main arm 201, the main arm 201 and the secondary arm 202 are linearly arranged and form a cantilever beam structure, and the rotation axis of the main arm 201 and the secondary arm 202 are vertical; when the two single-body barrier nets located on both sides of the crossed cable 102 are in the unfolded state, the secondary arms 202 opposite to each other on the two single-body barrier nets are in a buckled state.

[0052] like Figure 2 As shown, it should be noted that, since the main arm 201 and the auxiliary arm 202 form a cantilever beam structure, when forming a single-body barrier net, the single-body barrier net as a whole can also be regarded as a cantilever beam structure. In order to ensure that the two groups of single-body barrier nets located on both sides of the crossed cable 102 can be buckled in the same plane, the present invention is hingedly provided with a second driving member 10 on the main arm 201, and the piston end of the second driving member 10 is hingedly connected to the auxiliary arm 202, so that the auxiliary arm 202 can rotate with its hinge point as the center of the circle and keep the auxiliary arm 202 in a horizontal state. Figure 3 to Figure 2 Before the state change process, the second driving member 10 is used to drive the auxiliary arm 202 to rotate at a certain angle until the auxiliary arms 202 on the two sets of monomer barrier nets are in the same plane, and then the state change process can be carried out. Figure 3 to Figure 2 The change of state realizes the connection between the two sets of single barrier nets.

[0053] During the actual installation of the two sets of spanning components, the heights of the two sets of spanning components can be adjusted adaptively. This is a rough adjustment, which is intended to ensure that the heights of the two opposite support frames 1 and the two opposite swing arms 2 on both sides of the spanned cable 102 are basically consistent. The state after installation can be obtained by Figure 3 Then, Figure 3 to Figure 2 Before the state changes, based on the above rough adjustment, if Figure 3 In this state, the two opposing single barrier nets on both sides of the crossed cable 102 are already in the same plane state, and can be directly buckled, that is, Figure 3 to Figure 2 The change of state; if Figure 3 In the state, the relative single blocking nets on both sides of the crossed cable 102 are in a non-coplanar state, and the second driving member 10 is used to adjust the positions of the two opposite single blocking nets on both sides of the crossed cable 102. This is a fine adjustment, which is intended to ensure that the two opposite single blocking nets on both sides of the crossed cable 102 are in a non-coplanar state when the transition is completed. Figure 2 Before the state, they are arranged in the same plane to realize the buckling of two sets of single barrier nets.

[0054] At the same time, in order to ensure the stability of the spanning component when it is set in the corresponding place, the spanning component can be arranged to also include a traction rope 15 with one end connected to the scissor-type lifting bracket 13, and the other end of the traction rope 15 is provided with a ground nail for being inserted into the ground. By utilizing multiple ground nails and the traction rope 15 to pull the scissor-type lifting bracket 13 circumferentially, the scissor-type lifting bracket 13 can be ensured to be stable at the corresponding height.

[0055] like Figure 5 As shown, further, the buckling structure between the two groups of single barrier nets of the present invention can be set as follows: a collar 4 is set at the auxiliary arm 202 of one group of spanning components, and a hook 5 is set at the auxiliary arm 202 of the other group of spanning components. Both the collar 4 and the hook 5 can be adjusted to a horizontal state through the corresponding second driving member 10 to buckle the two. Of course, the buckling is a detachable connection. Figure 2 to Figure 3 During the transformation, the collar 4 and the hook 5 can be separated. Based on this, the buckle connection between the two groups of monomer barrier nets is not limited to the above-mentioned structure, and can also be set as other connecting parts in the prior art. In order to avoid cumbersomeness, this article will not repeat it here.

[0056] like Figure 4As shown, in order to improve the degree of automation in the construction of the two sets of crossing components and avoid more manual operations, a connecting shaft 6 for rotationally connecting to the top of the support frame 1 can be provided on the main arm 201, and the connecting shaft 6 and the main arm 201 are arranged in an L shape. A first driving member is provided on the support frame 1, and the first driving member is used to drive the connecting shaft 6 to rotate horizontally, that is, the first driving member can be used to drive the single barrier net to rotate.

[0057] The first driving member can be configured as follows: the first driving member includes a driving motor 7 fixedly mounted on the support frame 1, and a driving gear 8 is fixedly sleeved on the output shaft of the driving motor 7, and a driven gear ring 9 is fixedly sleeved on the adapter shaft 6, and the driven gear ring 9 is meshed with the driving gear 8 for transmission. Figure 3 In this state, the output shaft of the driving motor 7 can be driven to rotate, and then the driven gear ring 9 and the adapter shaft 6 will be rotated to realize the rotation of the single barrier net, that is, it can be completed automatically. Figure 3 to Figure 2 Transition of state.

[0058] like Figure 2-Figure 3 As shown, in order to strengthen the internal connection of the single barrier net, a supporting rod 11 can be connected between the two main arms 201, and the multiple supporting rods 11 in each group of crossing components are arranged linearly to form a straight rod part, and inclined rods 12 are provided at both ends of the straight rod part, and the two inclined rods 12 are arranged in an inverted eight shape in the vertical direction. By utilizing the setting of the inclined rods 12, the walking wire 103 can be restricted to the area formed by the two inclined rods 12, preventing the walking wire 103 from being dislodged from the crossing component during its movement.

[0059] Embodiment 2:

[0060] A method for using a scissor-type lifting span frame comprises the following steps:

[0061] Step 1: two groups of spanning components are respectively arranged on both sides of the spanned cable 102, and then the support frame 1 is lifted to a corresponding height by using the lifting parts thereon, until the two swing arms 2 arranged opposite to each other on the two groups of spanning components are located on the same horizontal plane, and the single barrier net composed of any two adjacent swing arms 2 on the same spanning component is in a stored state;

[0062] Step 2: Use the second driving member 10 to drive the auxiliary arm 202 to rotate and adjust until the two auxiliary arms 202 arranged opposite to each other on the two groups of spanning components are on the same horizontal plane, that is, the two monomer barrier nets arranged opposite to each other and in the storage state on the two groups of spanning components are on the same horizontal plane;

[0063] Step three: Use the first driving member to drive the swing arm 2 to rotate horizontally, so that the single-body barrier net changes from the stored state to the deployed state. During this state change process, the two single-body barrier nets arranged relatively to each other on the two groups of spanning components will be buckled by means of the ring 4 and the hook 5 to realize the connection of the two single-body barrier nets and complete the connection of the two groups of spanning components.

[0064] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.

During this state change process, the two single barrier nets arranged relatively on the two groups of spanning components will be buckled by means of the ring (4) and the hook (5), so as to realize the connection of the two single barrier nets and complete the connection of the two groups of spanning components.
