Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a hanging basket traveling system. Background Technology

[0002] The hanging basket is the main equipment in cantilever construction. Existing hanging basket traveling devices, due to the narrow bridge decks, use a limited number of main trusses, and each unit consists of a hydraulic pump and a hydraulic jack, driving only one main truss. Each unit requires two operators (one to operate the pump and one to monitor the jack). However, with increasingly wider and more complex bridge structures, more and more main trusses are needed. Using the existing hanging basket traveling devices would not only consume a large amount of manpower, but also make it difficult to guarantee the synchronization of movement of multiple main trusses, affecting normal construction.

[0003] The through-hole jack is mainly used in engineering construction in conjunction with prestressed anchorages and tensioning equipment. The through-hole jack is a double-acting jack that utilizes double hydraulic cylinders.

[0004] Chinese Patent CN 107447683 A discloses a hanging basket traveling device, comprising several main trusses, several traveling components, and a jacking component. Each main truss corresponds one-to-one with a traveling component. Each traveling component includes a track, a set of reverse-locking wheels, and a sliding seat. The track is fixed to the bridge surface. This device uses nuts to secure the seat support at the rear end of the jack, requiring manual tightening of the nuts for each movement, which is cumbersome. Therefore, there is a need to design an automatically moving hanging basket traveling system. Utility Model Content

[0005] The purpose of this utility model is to provide a hanging basket walking system that solves the technical problem of low automation and the need for manual labor in existing hanging basket walking systems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A hanging basket traveling system includes a hydraulic pump device, a reverse pulley, a through-hole jack, a sliding support, a traveling track, a threaded steel bar, and a main truss. The reverse pulley and the sliding support are mounted on the traveling track, and the main truss is mounted on the reverse pulley and the sliding support. One end of the threaded steel bar is fixedly mounted at the front end of the traveling track. The threaded steel bar passes through the through-hole jack, and the front end of the through-hole jack is fitted with the sliding support. An automatic thread-twisting device is mounted on the threaded steel bar and is located at the rear end of the through-hole jack. The automatic thread-twisting device serves as a support seat for the through-hole jack and rotates automatically.

[0008] Furthermore, the automatic thread-twisting device includes a motor, a rear support nut, a nut sleeve gear, a motor rotating shaft, and a rotating gear. The rear support nut is threadedly connected to the threaded steel bar, sleeved on the threaded steel bar, and in contact with the rear end of the through-hole jack. The nut sleeve gear is sleeved on the outer end of the rear support nut. The motor rotating shaft is connected to the motor, and the rotating gear is mounted on the motor rotating shaft and meshes with the rotating gear. The rotation of the motor drives the rear support nut to rotate forward or backward.

[0009] Furthermore, a front steel plate is provided at the front end of the walking track, and a threaded steel groove is provided at the upper end of the front steel plate. The threaded steel is placed in the threaded steel groove, and the front steel plate is connected to the front end of the walking track by bolts.

[0010] Furthermore, a cross plate is provided at the front end of the rebar, and the cross plate is welded and fixed to the rebar, and the cross plate is clipped onto the outside of the rebar channel.

[0011] Furthermore, the hydraulic pump device includes a switch, a hydraulic pump, and a trolley. The hydraulic pump is mounted on the trolley, the switch is mounted on the push handle of the trolley and controls the hydraulic pump, and the hydraulic pump is connected to the through-hole jack.

[0012] Furthermore, the trolley is equipped with a motor control circuit board, which is connected to the motor. The motor control circuit board is a PLC control board that controls the forward and reverse rotation of the motor. The forward and reverse rotation switch is located on the push handle of the trolley, and each press sets a fixed rotation distance.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0014] This utility model, by setting up an automatic screw-twisting device, allows the nut to automatically rotate and move forward as the manhole jack pushes forward and retracts. This achieves automatic nut rotation, eliminating the need for manual tightening of the nut after each push during the movement. Furthermore, the motor-driven rotation significantly improves efficiency and shortens the travel time of the hanging basket. The hydraulic pump station is a movable structure, avoiding obstruction during construction. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0019] like Figure 1-2 As shown, a hanging basket traveling system includes a hydraulic pump, a reverse-locking wheel 4, a through-hole jack 6, a sliding support 7, a traveling track 8, a threaded steel bar 9, and a main truss 12. The reverse-locking wheel 4 and the sliding support 7 are mounted on the traveling track 8, and the main truss 12 is mounted on the reverse-locking wheel 4 and the sliding support 7. One end of the threaded steel bar 9 is fixed to the front end of the traveling track 8, and the threaded steel bar 9 passes through the through-hole jack 6. The front end of the through-hole jack 6 is fitted against the sliding support 7. An automatic thread-twisting device 5 is provided on the threaded steel bar 9, located at the rear end of the through-hole jack 6. The automatic thread-twisting device 5 serves as a support seat for the through-hole jack 6 and rotates automatically. The automatic thread-twisting device 5 can automatically rotate a nut forward. The number of rotations per cycle can be set via program code to determine the distance traveled, which is the same as the forward movement distance of the through-hole jack 6.

[0020] In this embodiment of the utility model, such as Figure 2 As shown, the automatic thread-twisting device 5 includes a motor, a rear support nut 13, a nut sleeve gear 14, a motor rotating shaft 15, and a rotating gear 16. The rear support nut 13 is threadedly connected to the threaded steel bar 9, sleeved on the threaded steel bar 9, and contacts the rear end of the through-hole jack 6. The nut sleeve gear 14 is sleeved on the outer end of the rear support nut 13. The motor rotating shaft 15 is connected to the motor, and the rotating gear 16 is mounted on the motor rotating shaft 15 and meshes with the rotating gear 16. The rotation of the motor drives the rear support nut 13 to rotate forward or backward. The motor drives the nut to rotate by reversing its direction. The motor rotating shaft 15 and the rotating gear 16 are fixedly installed.

[0021] In this embodiment of the invention, a front steel plate 11 is provided at the front end of the traveling track 8. A threaded steel groove is provided at the upper end of the front steel plate 11, and a threaded steel bar 9 is disposed within the threaded steel groove. The front steel plate 11 is connected to the front end of the traveling track 8 by bolts. After one complete travel, the front steel plate 11 is disassembled and installed at the front end according to the laying pattern. This disassembly and installation process completes the movement of the suspended platform at a fixed distance with a single operation. A horizontal backboard can also be provided above the threaded steel groove to prevent the threaded steel bar 9 from shifting upwards.

[0022] In this embodiment of the invention, a horizontal plate 10 is provided at the front end of the threaded steel bar 9. The horizontal plate 10 is welded and fixedly installed to the threaded steel bar 9, and is snapped onto the outside of the threaded steel bar groove. The connection of the horizontal plate 10 is fully welded, and several reinforcing ribs are added to strengthen the connection.

[0023] In this embodiment of the utility model, such as Figure 1 As shown, the hydraulic pump device includes a switch 1, a hydraulic pump 2, and a trolley 3. The hydraulic pump 2 is mounted on the trolley 3, and the switch 1 is mounted on the push handle of the trolley 3 and controls the hydraulic pump 2. The hydraulic pump 2 is connected to the through-hole jack 6. The trolley 3 is an existing push-moving trolley, which can be disassembled and placed aside during construction to avoid obstructing the work.

[0024] In this embodiment of the invention, the trolley 3 is equipped with a motor control circuit board, which is connected to the motor. The motor control circuit board is a PLC control board, specifically a Siemens 200 PLC, which controls the forward and reverse rotation of the motor. A forward / reverse rotation switch is located on the push handle of the trolley 3; each press sets a fixed rotation distance. There are two buttons: forward and reverse. Control signals are sent to the PLC control board to control the motor's forward and reverse rotation, and the number of revolutions in each forward and reverse rotation is preset.

[0025] When the hanging basket needs to move, press switch 1 to pressurize the hydraulic pump 2 to push the through-hole jack 6 forward. Since the front end of the threaded steel bar 9 is fixed, and the rear end of the through-hole jack 6 is supported by the rear support nut 13, the through-hole jack 6 pushes the sliding support 7 forward. After pushing, release the pressure and the through-hole jack 6 retracts. At this time, there is a certain distance between the through-hole jack 6 and the sliding support 7. Then press the forward transmission button to control the motor to drive the rear support nut 13 to push the through-hole jack 6 forward until it is in contact with the sliding support 7 and stops, thus realizing the forward movement of the hanging basket.

[0026] Any matters not covered in this utility model are common knowledge.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
