[0003] The existing electric speed regulating hydraulic coupler relies on driving the scoop tube to control the amount of oil in the hydraulic coupler to control the torque and speed of the transmission. For example, the Chinese utility model patent "Linear electric speed regulating hydraulic coupler scoop tube driving mechanism" with patent number 201020032800.9 and authorization announcement number CN201705883U is arranged on a coupler frame provided with a scoop tube oil extraction chamber and an oil outlet, including: a scoop tube and a linear electric actuator, the scoop tube includes a scoop tube head and a scoop tube pull rod, the scoop tube head is sleeved to one end of the scoop tube pull rod, and the other end of the scoop tube pull rod partially penetrates the scoop tube oil extraction chamber; the linear electric actuator includes an output conduit, an output shaft, a mounting flange and a connecting sleeve, the output conduit is sleeved with the mounting flange, and the mounting flange is connected to the frame; the output shaft is arranged in the output conduit and penetrates the scoop tube oil extraction chamber, and the connecting sleeve is respectively connected to the output shaft and the scoop tube pull rod.

[0004] In actual use, the driving mechanism for driving the scoop tube to move may fail and need to be shut down for maintenance, and the shutdown of the hydraulic coupling will cause losses. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a manual driving tool for a scoop pipe of an electric speed regulating hydraulic coupler in view of the current status of the prior art, so as to ensure the normal operation of the hydraulic coupler when the driving mechanism fails.

[0006] The utility model solves the above technical problems by adopting a technical solution: a manual driving tool for a scoop tube of an electric speed regulating hydraulic coupler, wherein the length direction of the scoop tube is a first direction, and the scoop tube can move back and forth along the first direction under the action of a driving mechanism and extend and retract relative to the hydraulic coupler body; the manual driving tool comprises:

[0007] A clamping member, used for clamping the outer periphery of the scoop tube in the circumferential direction and located outside the hydraulic coupler body;

[0008] A bracket, used for being fixed relative to the fluid coupling body and located outside the fluid coupling body;

[0009] A screw rod extending in the first direction is constrained to the bracket in a manner that it can rotate around its own axis, and a transmission member is threadedly connected to the screw rod, and the transmission member is constrained together with the clamping member;

[0010] The guide rod extending along the first direction is passed through the through hole on the transmission member and is constrained together with the bracket, so that the transmission member can move along the extension direction of the guide rod together with the clamping member under the action of the rotational force of the screw rod.

[0011] In this way, the utility model drives the screw rod to rotate, thereby driving the transmission member on the screw rod and the clamping member constrained by the transmission member to move in the first direction, thereby manually controlling the movement of the scoop tube. Therefore, the utility model can manually drive the scoop tube to move when the driving mechanism for driving the scoop tube to move in the electric speed regulating hydraulic coupling fails to be repaired, thereby ensuring the normal operation of the hydraulic coupling.

[0014] At the same time, the free ends of the two transmission force-bearing rods are constrained together with the transmission member in a detachable manner.

[0015] In this way, the angle of the transmission force-bearing rod can be adjusted according to the position of the transmission member, so that the free end of the transmission force-bearing rod is constrained together with the transmission member.

[0016] To facilitate disassembly and assembly, preferably, the free end of each transmission force-bearing rod is constrained together with the transmission member by magnetic attraction.

[0017] Preferably, magnets are provided on the transmission member at positions corresponding to the free ends of the transmission force-bearing rods.

[0019] In this way, the substrate can be fastened to the end surface of the scoop tube flange by using the second bolts on the scoop tube flange, which is easy to operate and does not require the provision of other connecting structures or the change of the structure of the hydraulic coupler body.

[0020] In order to enable the substrate to be stably mounted on the spoon tube flange, preferably, there are at least two mounting holes, which are arranged corresponding to at least two of the plurality of second bolts.

[0021] Preferably, the mounting hole is U-shaped, and the U-shaped opening is used to face the center of the spoon tube flange and is used for the rod of the second bolt to pass horizontally. The design of the U-shaped mounting hole in the utility model can be applicable to spoon tube flanges of different sizes, and the second bolt can be arranged at a suitable position of the U-shaped mounting hole according to its position on the spoon tube flange, such as the second bolt can be arranged relatively close to the U-shaped opening of the U-shaped mounting hole, or relatively far from the U-shaped opening of the U-shaped mounting hole.

[0023] To facilitate driving the screw rod to rotate, preferably, one end of the screw rod passes through the end plate and is connected to a hand wheel for driving the screw rod to rotate.

[0024] Compared with the prior art, the utility model has the advantages that: the utility model drives the screw rod to rotate, thereby driving the transmission member on the screw rod and the clamping member constrained by the transmission member to move in the first direction, thereby manually controlling the movement of the scoop tube. Therefore, when the driving mechanism for driving the scoop tube to move in the electric speed regulating hydraulic coupling is faulty, the utility model can manually drive the scoop tube to move and ensure the normal operation of the hydraulic coupling.

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] like Figures 1 to 11 As shown, a preferred embodiment of the manual driving tool for the spoon tube of the electric speed regulating hydraulic coupling of the utility model is shown. The electric speed regulating hydraulic coupling is an existing structure, which includes a hydraulic coupling body, a spoon tube 1 and a driving mechanism 2. The hydraulic coupling body has a spoon tube flange 7, the central part of the spoon tube flange 7 is provided with a through hole 71, and the outer part of the spoon tube flange 7 is provided with a plurality of second bolts 72 at intervals along the circumferential direction. The length direction of the spoon tube 1 is the first direction, the spoon tube 1 is inserted in the central through hole 71 of the spoon tube flange 7, and the spoon tube 1 can move back and forth along the first direction under the action of the driving mechanism 2 and expand and contract relative to the hydraulic coupling body. The driving mechanism 2 is an existing structure, including a driving machine 21, a rocker arm 22 connected at one end to the power output end of the driving machine 21, and a connecting rod 23. The first end of the connecting rod 23 is connected to the other end of the rocker arm 22 through a transmission pin, and the second end of the connecting rod 23 (as the output end of the driving mechanism 2) is connected to the spoon tube 1 through a transmission pin. The power output by the driving machine 21 can be transmitted to the spoon tube 1 through the rocker arm and the connecting rod to drive the spoon tube 1 to move. At the same time, the second end of the connecting rod 23 can be separated from the spoon tube 1, so that when the driving mechanism 2 needs to be repaired due to a fault, the output end of the driving mechanism 2 can be separated from the spoon tube 1.

[0038] The manual drive tooling comprises a clamping member 3 , a bracket 4 , a screw rod 5 and a guide rod 6 .

[0039] Among them, Figure 1 , Figures 6 to 8As shown, the clamping member 3 is used to clamp the outer periphery of the spoon tube 1 along the circumferential direction and is located outside the main body of the hydraulic coupler. In this embodiment, the clamping member 3 is formed by two C-shaped clamping hoops 30 connected together, and the joint is connected by a first bolt 31. Each clamping hoop 30 is provided with a transmission force rod 32, and the first end of each transmission force rod 32 can be rotatably arranged on the corresponding clamping hoop 30 around a first axis extending along a first direction, and the second end is a free end 321. The free ends 321 of the two transmission force rods 32 can be relatively close to or away from each other as they rotate.

[0040] like Figures 1 to 4 , Figure 8 As shown, the bracket 4 is used to be fixed relative to the hydraulic coupling body and is located outside the hydraulic coupling body. In this embodiment, the bracket 4 includes a substrate 4a and an end plate 4b. The substrate 4a is used to be attached to the end surface of the spoon tube flange 7 and the periphery of the through hole 71, and the substrate 4a is provided with a mounting hole 41 for the rod of the second bolt 72 to pass through, so that the substrate 4a can be fastened to the end surface of the spoon tube flange 7 through the second bolt 72. Specifically, there are four mounting holes 41, the first mounting hole and the second mounting hole are respectively arranged corresponding to two of the plurality of second bolts 72, the third mounting hole is arranged adjacent to the first mounting hole, the fourth mounting hole is arranged adjacent to the second mounting hole, and the spacing distance between the third and fourth mounting holes is smaller than the spacing distance between the first and second mounting holes. As shown in the figure, when the radial dimensions of the spoon tube flange 7 are different and the spacing distances of the second bolts 72 are different, the third mounting hole and the fourth mounting hole can be used to correspond to two of the plurality of second bolts 72, or the first mounting hole and the fourth mounting hole (or the third mounting hole and the second mounting hole) can be arranged corresponding to two of the plurality of second bolts 72, which is specifically selected according to the position of the second bolts. At the same time, in this embodiment, each mounting hole 41 is U-shaped, and the U-shaped opening is used to face the center of the spoon tube flange 7 and is used for the rod of the second bolt 72 to pass through horizontally. In this way, it can be suitable for spoon tube flanges 7 of different sizes, and the second bolt 72 can be set at a suitable position corresponding to the U-shaped mounting hole according to its position on the spoon tube flange 7. For example, the second bolt 72 can be set relatively close to the U-shaped opening of the U-shaped mounting hole, and can also be set relatively far away from the U-shaped opening of the U-shaped mounting hole.

[0041] The end plate 4b is disposed opposite to the base plate 4a, and the two are connected by two connecting rods 4c extending along the first direction. Figure 1 , 2 , 10, 11.

[0042] The screw rod 5 extends along the first direction, and the two ends of the screw rod 5 are respectively inserted on the substrate 4a and the end plate 4b, so that the screw rod 5 can be constrained to rotate around its own axis on the bracket 4. At the same time, one end of the screw rod 5 passes through the end plate 4b and is connected to a hand wheel 51 for driving the screw rod 5 to rotate. The screw rod 5 is provided with a threaded transmission member 52 (the transmission member 52 is located between the substrate 4a and the end plate 4b, and the transmission member 52 is provided with a threaded hole 522 that matches the external thread on the screw rod 5). The transmission member 52 is provided with two magnets 521, so that it is constrained together with the free ends 321 of the two transmission force rods 32 by magnetic attraction. For details, please refer to Figure 1 , 5 .

[0043] like Figure 1 As shown, the guide rod 6 extends along the first direction and passes through the through hole 520 on the transmission member 52, and the two ends of the guide rod 6 are respectively supported on the base plate 4a and the end plate 4b, so that the transmission member 52 can move along the extension direction of the guide rod 6 with the clamping member 3 under the action of the rotational force of the screw rod 5.

[0044] In this way, when the driving mechanism 2 needs to be repaired, the substrate 4a can be first installed on the end surface of the spoon tube flange 7, the clamping member 3 can be clamped on the outer periphery of the spoon tube 1, the screw rod 5 and the guide rod 6 can be assembled to the bracket 4, and the transmission member 52 on the screw rod 5 and the free end of the transmission force rod 32 on the clamping member 3 can be magnetically attracted together to complete the assembly of the manual driving tool, and then the output end of the driving mechanism 2 can be separated from the spoon tube 1, and the screw rod 5 can be driven to rotate by manually driving the hand wheel 51, thereby driving the transmission member 51 on the screw rod 5 and the clamping member 3 constrained with the transmission member 51 to move along the first direction, thereby manually controlling the movement of the spoon tube 1. Therefore, the utility model can manually drive the spoon tube 1 to move and ensure the normal operation of the hydraulic coupling when the driving mechanism 2 in the electric speed regulation type hydraulic coupling is repaired. And when the output end of the driving mechanism 2 is separated from the spoon tube 1, the manual driving tool can stably support the spoon tube 1 to ensure the smooth operation of the coupler.

[0045] After the drive mechanism 2 is overhauled, the output end of the drive mechanism 2 is connected to the spoon tube 1, and then the above manual drive tooling is disassembled for easy operation.
