Description

Technical Field

[0001] The utility model relates to the field of trusses, in particular to a truss traveling device with staggered pulley installations. Background Art

[0002] In the truss field, the moving frame moves linearly along the length of the I-beam. During the movement, the second pulley contacts the vertical surface of the I-beam to achieve sliding between the moving frame and the I-beam.

[0003] During the installation of the device, the second pulley is first matched with the moving frame, and then the moving frame is matched with the I-beam. However, during the movement of the device, if the second pulley is damaged, the moving frame needs to be moved to the end of the I-beam, and the I-beam and the moving frame need to be separated before the second pulley can be replaced. In this way, during the movement, the I-beam and the moving frame are in hard contact for a long time, which may cause friction damage to the moving frame or the I-beam.

[0004] The above reason is that the second sliding and movable frames are connected by a combination of bolts and nuts. For example, when the bolt cooperates with the second pulley from top to bottom, the nut needs to be installed at the bottom of the bolt, and the distance between the second pulley and the horizontal part of the I-beam is small, which cannot meet the installation space of the nut; for another example, when the bolt cooperates with the second pulley from bottom to top, the length of the bolt is greater than the distance between the horizontal parts of the top frame and the I-beam, which cannot meet the entry space of the bolt.

[0005] In summary, how to realize the disassembly and assembly of the second pulley and the top frame or the bottom frame has become a problem that researchers in this field urgently need to solve. Utility Model Content

[0006] The technical problem to be solved by the utility model is: how to realize the disassembly and assembly of the second pulley and the top frame or the bottom frame;

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] The utility model discloses a truss walking device with pulleys staggeredly installed, comprising: an I-beam, which has a horizontal member and vertical members connecting the left and right ends of the horizontal member; a movable frame moving along the length direction of the I-beam, which has a side frame arranged on one side outside the vertical member, a top frame connected to the top of the side frame and horizontally arranged, and a bottom frame connected to the bottom of the side frame and horizontally arranged, wherein the top frame is located above the vertical member, and the bottom frame is located below the vertical member; a plurality of second pulleys with vertical axis directions, which are arranged on the bottom of the top frame by the cooperation of bolts and nuts and contact the inner side edges of the vertical member; and are arranged on the bottom of the bottom frame by the cooperation of bolts and nuts and contact the inner side edges of the vertical member; wherein the two second pulleys located above and below are staggered; a mounting hole is opened on the horizontal member, and the center of the second pulley passes through the mounting hole;

[0009] In this solution, the movable frame can move along the length direction of the I-beam. A second pulley is provided at the bottom of the top frame of the movable frame, and a second pulley is provided at the top of the bottom frame of the movable frame. The second pulley contacts the inner side surface of the vertical member. The upper and lower second pulleys are staggered along the length direction of the I-beam, and a mounting hole is provided on the I-beam.

[0010] When a second pulley is damaged, the second pulley moves to the mounting hole. After the maintenance personnel complete the disassembly of the bolts and nuts through the mounting hole, the second pulley is pulled out sideways, and a new second replacement pulley is inserted sideways to match the bolts and nuts again to replace the second pulley; the mounting hole provides space for disassembly and assembly of the bolts and nuts; since the upper and lower pulleys are staggered, the two second pulleys will not completely cover the upper and lower surfaces of the mounting hole, thereby realizing portable disassembly and assembly of the second pulley and the top frame or the bottom frame.

[0011] How to realize the movement of the movable frame along the I-beam? The utility model adopts the method of providing a rack on the outer side of the vertical member along the length direction of the I-beam; a first mounting seat is provided on the outer edge of one end of the side frame; a first rotating seat is rotatably connected to the first mounting seat; a motor is installed on the first rotating seat, and a first gear meshing with the rack is provided at the output end of the motor; a first guide seat is installed on the first mounting seat; a first guide rod with an arc structure, one end of which is connected to one side of the first rotating seat, and the other end passes through the first guide seat; a first elastic member is sleeved on the first guide rod, and its two ends respectively abut against the side edges of the first guide seat and the first rotating seat;

[0012] In this solution, the motor is arranged on the first rotating seat, and a gear is provided at the output end of the motor. The first rotating seat is rotatably arranged on the first mounting seat. The first rotating seat and the first mounting seat are connected by a first guide rod and a first guide seat. A first elastic member is provided on the first guide rod. Under the action of the first elastic member, the gear at the output end of the motor can always be in contact with the rack, reducing the possibility of idling of the motor gear due to the unevenness of the rack, thereby avoiding the risk of the moving frame stopping on the I-beam and not moving.

[0013] Similarly, in order to ensure that the gear and rack at the other end of the movable frame are always in contact, the utility model adopts a second mounting seat extending outward from the other end of the side frame; a second rotating seat, which is rotatably connected to the second mounting seat, and a second gear is rotatably provided at the bottom of the second rotating seat; a second guide seat, which is mounted on the second mounting seat; a second guide rod with an arc structure, one end of which is connected to one side of the second rotating seat, and the other end passes through the second guide seat; a second elastic member, which is sleeved on the second guide rod, and its two ends respectively abut against the side edges of the second guide seat and the second rotating seat;

[0014] The above-mentioned mounting structure is similar to the first mounting seat, the first rotating seat, etc., except that the motor is missing; in this way, the gears on both sides of the movable frame always cooperate with the racks under the action of the corresponding elastic members, avoiding the risk of the movable frame stopping on the I-beam and not moving.

[0015] To further illustrate how the I-shaped pulley cooperates with the movable frame, the present invention adopts a plurality of first pulleys with horizontal axis directions, which are arranged at the bottom frame and contact the bottom of the vertical member; and are arranged at the top frame and contact the top of the vertical member;

[0016] In this solution, the first pulley at the top of the vertical member cooperates with the top frame, and the first pulley at the bottom of the vertical member cooperates with the bottom frame. In this way, an additional first pulley is added between the I-wheel and the movable frame to avoid hard contact between the top and bottom of the movable frame and the vertical member.

[0017] When the second pulley is replaced and repaired, the second pulley is easily disassembled. The utility model adopts a locking seat provided at the bottom of the top frame; a locking rod is threadedly connected to the locking seat, and the locking rod is rotated to make the end of the locking rod contact the inner side surface of the vertical member. The movable frame here leans against the vertical surface to separate the second pulley from the inner wall of the vertical member;

[0018] When the I-beam and the movable frame need to be repaired, the locking rod is rotated to make the end of the locking rod contact the inner side of the vertical member, and the second pulley is separated from the inner wall of the vertical member, making it easy to replace the second pulley.

[0019] The beneficial effects of the utility model are as follows: the utility model is a truss walking device with staggered pulley installation, the moving frame can move along the length direction of the I-beam, a second pulley is provided at the bottom of the top frame of the moving frame, and a second pulley is provided at the top of the bottom frame of the moving frame, the second pulley contacts the inner side surface of the vertical member, the upper and lower second pulleys are staggered along the length direction of the I-beam, and a mounting hole is provided on the I-beam; when a second pulley is damaged, the second pulley moves to the mounting hole, and the maintenance personnel completes the disassembly of the bolts and nuts through the mounting hole to replace the second pulley; the mounting hole provides space for disassembly and assembly of the bolts and nuts; due to the staggered arrangement between the upper and lower pulleys, the two second pulleys will not completely cover the upper and lower surfaces of the mounting hole, thereby realizing portable disassembly and assembly of the second pulley and the top frame or the bottom frame.

[0030] When a second pulley 3 is damaged, the second pulley 3 is moved to the mounting hole 13. After the maintenance personnel complete the disassembly of the bolts and nuts through the mounting hole 13, the second pulley 3 can be replaced online; the mounting hole 3 provides space for disassembly and assembly of the bolts and nuts; since the upper and lower second pulleys 3 are staggered, the two second pulleys 3 will not completely cover the upper and lower surfaces of the mounting hole 13, thereby realizing the portable disassembly and assembly of the second pulley 3 and the top frame 22 or the bottom frame 23.

[0031] like Figure 1 、 3 As shown, how to realize the movement of the movable frame along the I-beam, the utility model adopts the outer side of the vertical member 12 to be provided with a rack 4 along the length direction of the I-beam 1; one end of the side frame 21 is extended outward to be provided with a first mounting seat 51; a first rotating seat 52 is rotatably connected to the first mounting seat 51; a motor 53 is mounted on the first rotating seat 52, and an output end of the motor is provided with a first gear 54 engaged with the rack 4; a first guide seat 55 is mounted on the first mounting seat 51; a first guide rod 56 of an arc structure, one end of which is connected to one side of the first rotating seat 51, and the other end passes through the first guide seat 55; a first elastic member 57 is sleeved on the first guide rod 56, and its two ends are respectively against the side edges of the first guide seat 55 and the first rotating seat 52;

[0032] In this solution, the motor is arranged on the first rotating seat, and a gear is provided at the output end of the motor. The first rotating seat is rotatably arranged on the first mounting seat. The first rotating seat and the first mounting seat are connected by a first guide rod and a first guide seat.
