Abstract

The application relates to a reversing operating mechanism, a hydraulic power assembly and a hydraulic climbing formwork device. When the end part of the bearing ratchet block is in the process of withdrawing from the guide groove, the bearing shaft is in transmission connection with the anti-falling member through the first driving member and the second driving member, and the bearing shaft rotates and drives the first driving member to drive the anti-falling member to extend into the guide groove. When the end part of the bearing ratchet block is positioned in the process of extending into the guide groove, the bearing shaft rotates and drives the second driving piece to drive the anti-falling piece to withdraw from the guide groove. The first driving piece and the second driving piece are driven by the bearing shaft to be matched with the anti-falling piece, so that the anti-falling piece extends out of the guide groove after the switching is completed between two adjacent hanging tongues of the guide rail in the process of switching the bearing ratchet block. Therefore, the falling prevention piece can effectively prevent the support assembly or the guide rail from losing support and slipping, and prevent falling accidents. The extension and retraction of the anti-falling member do not need to be controlled independently, so that the convenience of operation and the safety in the climbing process are improved.

Description

Reversing operating mechanism, hydraulic power assembly and hydraulic climbing formwork device

Technical Field

The application relates to the technical field of building construction equipment, in particular to a reversing operating mechanism, a hydraulic power assembly and a hydraulic climbing formwork device.

Background

In the field of bridge building construction, particularly in the pouring construction of high-rise structures such as bridge pier columns, a hydraulic climbing formwork device is increasingly applied to bridge engineering projects because of high-efficiency working capacity of the hydraulic climbing formwork device, namely, the hydraulic climbing formwork device can self-climb without lifting by hoisting machinery.

The hydraulic climbing formwork device comprises a climbing assembly, a bracket assembly, a formwork assembly, a hydraulic power assembly and the like, wherein the hydraulic power assembly provides power for climbing the bracket assembly and the formwork assembly layer by layer. The hydraulic power assembly of the traditional hydraulic climbing die device comprises a hydraulic oil cylinder, an upper reversing box and a lower reversing box, and two working states can be freely adjusted to realize climbing of a guide rail of the climbing assembly or upward climbing of a bracket assembly and a template assembly by switching ratchet blocks in the upper reversing box and the lower reversing box. Generally, an operator manually rotates a reversing handle on the reversing box to drive the ratchet block to rotate and reverse, so that the climbing state is converted. Or a hydraulic cylinder, a pneumatic cylinder and other devices are adopted to drive the ratchet block in the reversing box to rotate and reverse. For example, after the guide rail of the climbing assembly is fixed on a building elevation through the wall-attached hanging seat, the ratchet blocks in the upper reversing box and the lower reversing box are rotationally adjusted so that the bracket assembly can move upwards relative to the guide rail; when the support assembly climbs to the top end of the guide rail, the support assembly is hung on the wall-attached hanging seat, and then the ratchet blocks in the upper reversing box and the lower reversing box are rotationally adjusted, so that the guide rail can move upwards relative to the support assembly.

When the hydraulic climbing die device performs reversing operation, the switching of the upper reversing box and the lower reversing box needs to be strictly controlled, and the ratchet blocks of the upper reversing box and the lower reversing box can be switched only after at least one of the bracket assembly or the guide rail is fixed, otherwise, the bracket assembly or the guide rail can lose support and slip, and accidents occur. However, when the traditional hydraulic climbing die device performs reversing operation, no matter manual operation or automatic operation such as control hydraulic cylinder exists, the probability of misoperation exists, and thus potential safety hazards of falling can be caused.

Referring to fig. 3 to 6, in one embodiment, the reversing operation mechanism 302 includes a reversing box 310, a bearing assembly 320, and a reversing assembly 330, where a guide slot 311 for installing the guide rail 101 is formed on the reversing box 310; the bearing assembly 320 comprises a bearing ratchet block 321 and a bearing shaft 322, and the bearing ratchet block 321 is rotatably arranged in the reversing box body 310 through the bearing shaft 322; the reversing assembly 330 is disposed on the reversing box 310, and the reversing assembly 330 is configured to control the bearing shaft 322 to rotate to drive the bearing ratchet block 321 to switch between a rail climbing state and a bracket climbing state, where the bearing ratchet block 321 extends into the guide slot 311 at the end of the bearing ratchet block 321.

In one embodiment, along the length direction of the guide rail 101, a plurality of hanging tongues 103 are disposed on the guide rail 101 at intervals. One side of the guide rail 101 is arranged in the embedded part unit 102 in a penetrating way, and the other side of the guide rail is arranged in the guide groove 311 of the reversing box body 310 in a penetrating way. In the rail climbing state, the end of the bearing ratchet block 321 extends out of the guide groove 311 and can be abutted against the lower end face of the hanging tongue 103, and in the bracket climbing state, the end of the bearing ratchet block 321 extends out of the guide groove 311 and can be abutted against the upper end face of the hanging tongue 103.

When in use, the embedded part unit 102 is used for being fixed on the outer wall of a building, the bracket assembly 20 is hung on the embedded part unit 102, one side of the guide rail 101 is penetrated in the embedded part unit 102, and the other side is penetrated in the guide groove 311 of the reversing box body 310 and hung on the embedded part unit 102. When climbing is needed, the reversing assembly 330 controls the bearing shaft 322 to rotate so as to drive the bearing ratchet block 321 to rotate, and when the end part of the bearing ratchet block 321 extends out of the guide groove 311 and is abutted on the lower end surface of the hanging tongue 103 of the guide rail 101, switching to the guide rail climbing state is completed, and the hydraulic power piece 301 drives expansion and contraction, so that climbing of the guide rail 101 can be completed. When the track 101 finishes climbing, the load-bearing ratchet block 321 needs to be switched to a support climbing state, and the end part of the load-bearing ratchet block 321 extends out of the guide groove 311 and abuts against the upper end surface of the hanging tongue 103 of the track 101. The upper reversing operating mechanism 302 and the lower reversing operating mechanism 302 of the hydraulic power assembly 30 are respectively provided with a bearing ratchet block 321, and the two bearing ratchet blocks 321 are required to be reversed to the same state, so that the function conversion of the lifting bracket assembly 20 or the guide rail 101 is realized. The bearing ratchet block 321 of the reversing operating mechanism 302 is always supported on the hanging tongue 103 of the guide rail 101 in the actual lifting process.

In an embodiment, the reversing assembly 330 includes a reset elastic member and a switching member, the switching member is connected to the bearing shaft 322, the switching member is used for controlling the bearing shaft 322 to rotate so as to drive the bearing ratchet block 321 to switch between a track climbing state and a support climbing state, one end of the reset elastic member is connected to the bearing ratchet block 321, the other end of the reset elastic member is connected to the reversing box 310, and the reset elastic member is used for providing an elastic force for the bearing ratchet block 321 to reset to the track climbing state or the support climbing state. Specifically, in the rail climbing state, the upper end of the bearing ratchet block 321 abuts against the lower end face of the hanging tongue 103 of the rail 101, and in the bracket climbing state, the lower end of the bearing ratchet block 321 abuts against the upper end face of the hanging tongue 103 of the rail 101. The switching of the setting state of the bearing ratchet block 321 is conveniently realized by arranging the switching piece, and the reset of the bearing ratchet block 321 in the climbing process is conveniently realized by arranging the reset elastic piece, so that the climbing reliability is improved.

In this embodiment, the switching member may be a hydraulic cylinder, an air cylinder or a motor, etc., so as to realize automatic rotation of the bearing shaft 322, and further realize automatic switching of different states of the bearing ratchet block 321, thereby improving convenience of operation. In other embodiments, the switching member may be a rotating handle, which is connected to the bearing shaft 322, and the rotating handle is manually operated to automatically switch different states of the bearing ratchet 321.

Referring to fig. 3 to 6, in an embodiment, the reversing operation mechanism 302 further includes a fall protection assembly 340, where the fall protection assembly 340 includes a first driving member 341, a second driving member 342, and a fall protection member 343, and the bearing shaft 322 is in transmission connection with the fall protection member 343 through the first driving member 341 and the second driving member 342; when the end of the bearing ratchet 321 is in the process of withdrawing from the guide groove 311, the first driving piece 341 drives the falling preventing piece 343 to extend into the guide groove 311; the second driving member 342 drives the falling preventing member 343 to exit the guide slot 311 while the end of the bearing ratchet 321 is in the process of extending into the guide slot 311. Specifically, when the load-bearing ratchet block 321 is switched between the track climbing state and the bracket climbing state, the anti-falling member 343 can extend between two adjacent hanging tongues 103.

When climbing is required, the reversing assembly 330 controls the bearing shaft 322 to rotate to drive the bearing ratchet block 321 to switch to the track climbing state, as the bearing shaft 322 is in transmission connection with the anti-falling member 343 through the first driving member 341 and the second driving member 342, as shown in fig. 3 to 4, when the end of the bearing ratchet block 321 is in the process of exiting from the guide slot 311, the bearing shaft 322 rotates and drives the first driving member 341 to drive the anti-falling member 343 to extend into the guide slot 311, so that the anti-falling member 343 extends between two adjacent hanging tongues 103 of the guide track 101. As shown in fig. 4 to 5, when the end of the bearing ratchet 321 is in the process of extending into the guide slot 311, the bearing shaft 322 rotates and drives the second driving member 342 to drive the anti-falling member 343 to exit from the guide slot 311. The end of the bearing ratchet block 321 extends into the guide groove 311 and abuts against the lower end surface of the hanging tongue 103 of the guide rail 101, and after the guide rail climbing state is switched, the anti-falling member 343 completely exits the guide groove 311. When the climbing of the guide rail 101 is completed, the load-bearing ratchet block 321 needs to be switched to a support climbing state, and similarly, the anti-falling member 343 extends between two adjacent hanging tongues 103 of the guide rail 101 in the switching process, and after the switching is completed, the anti-falling member 343 exits from the guide groove 311. The reversing operation mechanism 302 drives the first driving member 341 and the second driving member 342 to cooperate with the anti-falling member 343 through the bearing shaft 322, so that the anti-falling member 343 extends between two adjacent hanging tongues 103 of the guide rail 101 in the process of switching the state of the bearing ratchet block 321, and after the switching is completed, the anti-falling member 343 exits the guide groove 311. Therefore, in the switching process, if one of the guide rail 101 or the support assembly 20 is not fixed, the falling prevention member 343 can effectively prevent the support assembly 20 or the guide rail 101 from falling off due to the loss of support, thereby preventing the falling accident. The extension and retraction of the falling prevention member 343 is realized by the rotation control of the first driving member 341, the second driving member 342 and the bearing ratchet block 321, and no separate control is needed, thereby further improving the convenience of operation and the safety during climbing.

In one embodiment, the first driving member 341 is rotatably disposed on the reversing box 310, the first driving teeth 344 are disposed on an outer wall of the first driving member 341, the second driving member 342 is rotatably disposed on the reversing box 310, and the second driving teeth 345 are disposed on an outer wall of the second driving member 342. The first driving teeth 344 and the second driving teeth 345 facilitate the driving of the telescopic movement of the falling protector 343.

Calculating hydraulic power output: the hydraulic power unit 301 of the hydraulic power assembly 30 is composed of a plurality of volume speed-regulating hydraulic circuits, the volume speed-regulating hydraulic circuits drive a unidirectional constant delivery pump by a servo motor to supply oil to the hydraulic system, and the rotation speed of the pump is controlled by changing the rotation speed of the servo motor through a frequency converter, so that the displacement of the constant delivery pump is controlled. Based on the output values of the PID controllers, in combination with characteristics and parameters of the hydraulic system (e.g., cylinder area, pump displacement, rotational speed, etc.), the desired hydraulic power output is calculated, which typically involves some hydraulic calculations such as flow, applied force, power, etc.
