Description

[0003] However, the existing connecting rod device still has obvious limitations in transporting the rod body to the specified position and implementing the assembly. Since the diameters of the rod bodies to be assembled in the field differ significantly from each other, and the clamping structure of the existing connecting rod device is generally made of rigid metal material, the clamping surface of the clamping structure cannot be completely fitted to the outer wall surface of the rod body when facing different diameter rod bodies, and the actual contact area between the clamping structure and the rod body is thus greatly reduced. During the control of the movement of the rod body with the connecting rod device as a whole, the vibration generated by the operation of the connecting rod device is directly transmitted to the clamping structure through the rigid transmission chain, thereby inducing an indiscernible position deviation of the rod body relative to the clamping structure, resulting in that the connecting rod device can no longer use the spatial coordinate of the clamping structure as a reliable basis for the real position of the rod body, and finally seriously slowing down the assembly rhythm of the connecting rod device for the rod body and significantly reducing the overall assembly efficiency. In view of this, a connecting rod device for construction operation is proposed. SUMMARY

DETAILED DESCRIPTION

[0031] In order to further illustrate the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the preferred embodiments and the drawings.

[0032] Please refer to Figures 1-10The embodiment provides a connecting rod device for construction operation, which comprises a clamping jaw structure 1 and a moving device 2, the clamping jaw structure 1 is arranged on the moving device 2, a clamping surface of the clamping jaw structure 1 is formed with a circular clamping space 101 for clamping a round rod; the clamping jaw structure 1 is used for clamping a rod body, and the moving device 2 is used for driving the clamping jaw structure 1 to move, so that the rod body is transported. The connecting rod device further comprises an abutting assembly 3, the clamping surface of the clamping jaw structure 1 is provided with an abutting groove hole 102, the abutting groove hole 102 is arranged along the axis direction of the clamping surface of the clamping jaw structure 1, the abutting groove hole 102 and the clamping space 101 are in communication with each other, and the abutting assembly 3 comprises a plurality of telescopic rods 301, the plurality of telescopic rods 301 are arranged in the abutting groove hole 102 along the axis direction of the abutting groove hole 102 at equal intervals, the telescopic rod 301 has a telescopic structure, one end of the telescopic rod 301 is connected with the end face of the abutting groove hole 102, and the other end of the telescopic rod 301 can lock or release the abutting and fitting relationship with the round rod. When the clamping jaw structure 1 clamps the rod body, the clamping surface of the clamping jaw structure 1 cannot completely fit on the outer side wall surface of the rod body due to the fact that the clamping space 101 is circular. Then, the telescopic rod 301 starts to work, the telescopic end of the telescopic rod 301 moves in the direction away from the abutting groove hole 102, the telescopic rod 301 and the rod body are in abutting and fitting cooperation, the contact area between the clamping jaw structure 1 and the rod body is increased, and it is ensured that the clamping jaw structure 1 can stably clamp the rod body. Even if the clamping jaw structure 1 vibrates, the position of the rod body relative to the clamping jaw structure 1 will not be offset. After the moving device 2 moves the rod body to a specified position, the position of the clamping jaw structure 1 can be accurately positioned to the position of the rod body, so that the subsequent assembly effect of the clamping jaw structure 1 on the rod body is facilitated, and the assembly speed and efficiency of the rod body are improved. The problem that, during control of the rod body to move together with the connecting rod device, vibration generated during operation of the connecting rod device is directly transmitted to the clamping structure through a rigid transmission chain, and then the position of the rod body relative to the clamping structure is offset, so that the connecting rod device cannot use the space coordinates of the clamping structure as reliable basis for the real position of the rod body, and finally the assembly rhythm of the connecting rod device on the rod body is seriously slowed down and the overall assembly efficiency is significantly reduced.

[0033] Specifically, the clamping space 101 of the clamping jaw structure 1 is changeable, which can ensure that the clamping jaw structure 1 can clamp rod bodies of different diameters; based on this, the clamping jaw structure 1 of the present scheme includes a connecting plate 103, a rotating jaw 104 and a fixed jaw 105, the connecting plate 103 is connected with the moving device 2, the fixed jaw 105 is arranged at one end of the connecting plate 103, one end of the rotating jaw 104 is rotatably connected with the connecting plate 103, the rotating jaw 104 and the fixed jaw 105 are both matched with clamping surfaces, the clamping surface of the rotating jaw 104 and the clamping surface of the fixed jaw 105 together form the clamping space 101; the abutting assembly 3 is provided with two groups, the two groups of abutting assemblies 3 are respectively matched with the rotating jaw 104 and the fixed jaw 105, and any abutting assembly 3 is arranged in the abutting slot hole 102 of the rotating jaw 104 or the fixed jaw 105; by arranging the rotatable rotating jaw 104, when the rotating jaw 104 rotates along the hinge point thereof and the connecting plate 103, the position of the clamping surface of the rotating jaw 104 can be changed, thereby changing the distance between the clamping surface of the fixed jaw 105 and the clamping surface of the rotating jaw 104, and thereby changing the size of the clamping space 101. It is worth noting that the abutting assembly 3 of the present scheme is provided with two groups, the fixed jaw 105 and the rotating jaw 104 are both provided with the abutting slot hole 102, and the two groups of abutting assemblies 3 are arranged in the abutting slot holes 102 of the fixed jaw 105 and the rotating jaw 104. It is worth noting that, in order to improve the contact area of the clamping jaw structure 1 with the rod body, the clamping surface of the rotating jaw 104 and the clamping surface of the fixed jaw 105 are both arranged in a circular arc shape.

[0034] Specifically, the telescopic rod 301 of the present scheme includes an internal hollow fixed rod 302, a sliding rod 303 and a telescopic spring 304, the fixed rod 302 is arranged on the end face in the abutting slot hole 102, one end of the sliding rod 303 is slidably arranged in the fixed rod 302, the telescopic spring 304 is arranged in the fixed rod 302, and the two ends of the telescopic spring 304 are respectively connected with the fixed rod 302 and the sliding rod 303; by arranging the movable sliding rod 303, the sliding rod 303 can lock or release the abutting and fitting relationship with the rod body, and the telescopic spring 304 is used to control the contraction and reset of the sliding rod 303.

[0035] According to the description of the above embodiment, in order to control the extension of the sliding rod 303, the fixed rod 302 is provided with a pushing groove hole 3021, the telescopic rod 301 further comprises a pushing rod 305, the axis direction of the pushing groove hole 3021 is parallel to the axis direction of the fixed rod 302, the pushing rod 305 is connected with the sliding rod 303, the pushing rod 305 is sealingly arranged in the pushing groove hole 3021, and the hydraulic assembly 4 is further arranged in communication with the pushing groove hole 3021 to control the sliding of the pushing rod 305. By arranging the hydraulic assembly 4, the hydraulic assembly 4 sends hydraulic oil into the pushing groove hole 3021, and under the pushing of the hydraulic oil, the pushing rod 305 is smoothly controlled to slide away from the fixed rod 302. Since the pushing rod 305 is connected with the sliding rod 303, the extension of the sliding rod 303 is smoothly realized. In addition, it is worth noting that the hydraulic assembly 4 is arranged in two groups, and the two groups of hydraulic assemblies 4 are correspondingly matched with the two groups of abutting assemblies 3. Any hydraulic assembly 4 is connected with the corresponding abutting assembly 3.

[0036] In order to ensure the connection between the hydraulic assembly 4 and the clamping jaw structure 1, the clamping jaw structure 1 is further provided with a hydraulic groove hole 106, a plurality of communication holes 107 and an oil inlet 108. The plurality of communication holes 107 are one-to-one matched with the plurality of telescopic rods 301. Any communication hole 107 is in communication with the hydraulic groove hole 106 and the abutting groove hole 102, respectively. The fixed rod 302 is sealingly arranged in the communication hole 107. The pushing groove hole 3021 is in communication with the hydraulic groove hole 106. The two ends of the oil inlet 108 are in communication with the hydraulic assembly 4 and the hydraulic groove hole 106, respectively. Through such arrangement, when the hydraulic assembly 4 sends hydraulic oil, the hydraulic oil enters the hydraulic groove hole 106 through the oil inlet 108, and then the hydraulic oil in the hydraulic groove hole 106 enters the fixed rod 302 through the pushing groove hole 3021, drives the pushing rod 305 to slide, and then realizes the extension of the sliding rod 303. It is worth noting that due to the sealing cooperation between the fixed rod 302 and the communication hole 107, the hydraulic oil in the hydraulic groove hole 106 cannot overflow out of the abutting groove hole 102 through the communication hole 107, so as to ensure that the hydraulic oil does not leak.

[0037] Specifically, the hydraulic assembly 4 comprises a hydraulic tank filled with hydraulic oil, a hydraulic pump and an oil delivery pipe 403. The hydraulic tank and the hydraulic pump are arranged on the moving device 2. The two ends of the hydraulic pump are in communication with the hydraulic tank and one end of the oil delivery pipe 403, respectively. The other end of the oil delivery pipe 403 is in communication with the oil inlet 108. By arranging the hydraulic pump, when the hydraulic pump starts to work, the hydraulic oil in the hydraulic tank is pumped into the oil inlet 108.

[0038] According to the description of the above embodiment, in combination with the specific use occasion of the device, it is known that the reasons for the position deviation of the rod body relative to the jaw structure 1 are not only the insufficient contact area between the jaw structure 1 and the rod body, but also the vibration generated when the moving device 2 moves, which is transmitted to the jaw structure 1 and also causes the position deviation of the rod body relative to the jaw structure 1. Based on this, in order to weaken the vibration transmitted by the moving device 2 to the jaw structure 1, the present scheme further includes a connecting rod 5 and a plurality of reinforcing rods 6. The two ends of the connecting rod 5 are respectively connected with the connecting plate 103 and the output end of the moving device 2. The connecting rod 5 is provided to ensure the connection between the jaw structure 1 and the moving device 2. The plurality of reinforcing rods 6 are arranged around the connecting rod 5 at equal angles along the axial direction of the connecting rod 5. The reinforcing rod 6 includes a shock absorbing rod 601, a sliding shaft 602 and a sliding block 603. The sliding groove hole 6011 is coaxially opened in the shock absorbing rod 601. The sliding block 603 and the sliding shaft 602 are slidably arranged in the sliding groove hole 6011. The two ends of the sliding shaft 602 are respectively connected with the sliding block 603 and the output end of the moving device 2. One end of the shock absorbing rod 601 is connected with the connecting plate 103. By providing the reinforcing rod 6, the sliding block 603 absorbs the vibration near the connecting rod 5, realizes the sliding of the sliding block 603 in the shock absorbing rod 601, converts the vibration into mechanical energy of the sliding block 603 sliding along the shock absorbing rod 601, realizes the utilization of vibration energy, and further achieves the effect of weakening the vibration force transmitted by the moving device 2 to the jaw structure 1, avoids the vibration force transmitted to the jaw structure 1 being too strong, and avoids the situation that the position deviation of the rod body relative to the jaw structure 1 occurs.

[0039] According to the description of the above embodiment, in order to further enhance the effect of reinforcing rod 6 to consume vibration energy, the hydraulic assembly 4 of the present scheme includes a communication pipe 604, the clamping jaw structure 1 is also provided with a communication port 109 which is in communication with the hydraulic groove hole 106, the shock absorbing rod 601 is provided with an oil inlet port 6012 which is in communication with the sliding groove hole 6011, and the two ends of the communication pipe 604 are in communication with the communication port 109 and the oil inlet port 6012 respectively, so that the hydraulic oil can lock or release the matching relationship of filling in the sliding groove hole 6011; by providing the communication pipe 604, the excess hydraulic oil in the hydraulic groove hole 106 will overflow into the sliding groove hole 6011 through the communication pipe 604; it should be noted that since the sliding block 603 is slidably and sealingly arranged in the sliding groove hole 6011, the sliding block 603 divides the sliding groove hole 6011 into a damping space and a sliding space, and the damping space is in communication with the oil inlet port 6012, so that the hydraulic oil in the sliding groove hole 6011 is actually located in the damping space. After the damping space is filled with hydraulic oil, since the hydraulic oil has the characteristic of being compressed, when the vibration force is transmitted to the reinforcing rod 6, the sliding shaft 602 will drive the sliding block 603 to slide, thereby compressing the hydraulic oil and converting the vibration force transmitted by the moving device 2 to the sliding shaft 602 into the force of the sliding shaft 602 compressing the hydraulic oil, successfully converting the vibration force into hydraulic internal energy, and further improving the effect of the reinforcing rod 6 to consume vibration energy.

[0040] However, it should be noted that due to the existence of the communication pipe 604 in the scheme, the hydraulic tank hole 106 and the damping space are connected with each other, and such a setting may have a problem that when the sliding block 603 slides due to vibration, the sliding block 603 slides away from the damping rod 601, thereby causing the space in the damping space to be greater than the volume of the hydraulic oil, finally weakening the adhesion force of the sliding rod 303 to the rod body, and also causing the position of the rod body relative to the jaw structure 1 to be offset; based on this, the sliding block 603 of the scheme is a telescopic structure, the sliding block 603 can change its width size by telescoping, and the width of the sliding groove hole 6011 decreases along the axial direction of the damping rod 601 from the connecting plate 103 to the moving device 2, and the cross-sectional shape of the sliding block 603 is the same as that of the sliding groove hole 6011; through such a setting, in the normal state, when the sliding block 603 slides in the sliding groove hole 6011, the width of the sliding block 603 changes with the change of the width of the sliding groove hole 6011; after the hydraulic tank hole 106 and the damping space are filled with hydraulic oil, the width of the sliding block 603 can only be widened or remain unchanged, and cannot continue to be reduced; such a setting can only limit the sliding block 603 to slide towards the damping rod 601 or keep the position of the sliding block 603 unchanged when the vibration is transmitted to the sliding block 603, so as to ensure that the force of the sliding rod 303 to the rod body will increase or remain unchanged when the sliding block 603 is vibrated, and will not decrease.

[0041] Further, the sliding block 603 of the scheme includes an internal hollow sliding shell 6031, a connecting shell 6032 and a sliding spring 6033, the sliding groove hole 6011 includes a first groove hole 60111 and a second groove hole 60112 which are connected with each other, the sliding shell 6031 is slidably arranged in the first groove hole 60111, the connecting shell 6032 is slidably arranged in the second groove hole 60112, the sliding shell 6031 is provided with a connecting groove hole 60311, one end of the connecting shell 6032 is slidably arranged in the connecting groove hole 60311, the sliding spring 6033 is arranged in the connecting groove hole 60311, and the two ends of the sliding spring 6033 are connected with the sliding shell 6031 and the connecting shell 6032 respectively; it should be noted that the axial direction of the connecting groove hole 60311 and the axial direction of the second groove hole 60112 are arranged perpendicular to each other; through such a setting, the connecting shell 6032 is slidably arranged in the sliding groove hole 6011, thereby realizing the change of the width of the sliding block 603.

[0042] In addition, in order to ensure that the sliding block 603 is slidably sealed in the sliding groove hole 6011, the cross-sectional shape of the sliding shell 6031 is equal to the cross-sectional shape of the first groove hole 60111; the cross-sectional shape of the connecting shell 6032 extending out of the sliding shell 6031 is equal to the cross-sectional shape of the second groove hole 60112; such arrangement ensures that the sliding shell 6031 and the first groove hole 60111 are in a slidably sealed fitting relationship; similarly, the connecting shell 6032 and the second groove hole 60112 can also be in a slidably sealed fitting relationship; at the same time, in order to ensure that the connecting shell 6032 and the sliding shell 6031 are in a slidably sealed state, the cross-sectional shape of the side of the connecting shell 6032 is equal to the cross-sectional shape of the connecting groove hole 60311; and, in order to adapt to the situation that the width of the connecting shell 6032 changes during the sliding of the sliding block 603, the width of the second groove hole 60112 decreases from the direction of the connecting plate 103 to the mobile device 2.

[0043] In addition, in order to realize the sealed fitting relationship between the sliding block 603 and the sliding groove hole 6011, the present scheme further comprises a first sealing ring 7, which is attached to the inner side wall of the shock absorbing rod 601, and the first sealing ring 7 is distributed in the sliding groove hole 6011. By providing the first sealing ring 7, the fitting relationship between the sliding block 603 and the sliding groove hole 6011 is realized; at the same time, since the first sealing ring 7 is distributed in the sliding groove hole 6011, that is, the first sealing ring 7 is attached to the first groove hole 60111 and the second groove hole 60112, the sliding shell 6031 and the first groove hole 60111 are in a sealed fitting arrangement; and the connecting shell 6032 and the second groove hole 60112 are in a sealed fitting arrangement.

[0044] Similarly, in order to realize the sealed fitting relationship between the connecting shell 6032 and the sliding shell 6031, the present scheme further comprises a second sealing ring 8, which is attached to the inner side wall of the sliding shell 6031, and the second sealing ring 8 is distributed in the connecting groove hole 60311. By providing the second sealing ring 8, the fitting relationship between the connecting shell 6032 and the sliding shell 6031 is realized.

[0045] According to the description of the above embodiment, in order to ensure that the width of the sliding block 603 can only be widened or remain in the current state, but cannot continue to be smaller after the hydraulic tank hole 106 and the damping space are filled with hydraulic oil, the sliding block 603 further comprises a sealing rod 605, the sliding shell 6031 is further provided with a sealing groove hole 60312 and a communication groove hole 60313, the axis direction of the sealing groove hole 60312 is parallel to the sliding direction of the connecting shell 6032 relative to the sliding shell 6031, the sealing rod 605 is slidably arranged in the sealing groove hole 60312, one end of the sealing rod 605 is connected with the connecting shell 6032, and the two ends of the communication groove hole 60313 are in communication with the sliding groove hole 6011 and the sealing groove hole 60312 respectively; by being provided with the communication groove hole 60313, since the two ends of the communication groove hole 60313 are in communication with the damping space and the sealing groove hole 60312 respectively, this makes the hydraulic oil in the damping space can flow into the sealing groove hole 60312 through the communication groove hole 60313, and then realizes that the hydraulic oil drives the sealing rod 605 to slide, and finally controls the sliding of the connecting shell 6032; therefore, when the hydraulic tank hole 106, the damping space and the communication groove hole 60313 are filled with hydraulic oil, the connecting shell 6032 which can slide freely can only slide in the direction of extending out of the sliding shell 6031, or the connecting shell 6032 no longer continues to slide. It is worth noting that when the hydraulic oil is filled, the sliding distance of the connecting shell 6032 along the axis direction of the second groove hole 60112 is in millimeter level.

[0046] Specifically, the hydraulic assembly 4 further comprises a one-way valve 404, a switch valve 402 and an oil return pipe 401, the one-way valve 404 is sealingly arranged on the oil inlet 108, the damping rod 601 is further provided with an oil return port 6013 in communication with the sliding groove hole 6011, the oil return port 6013 is located in the damping space, the switch valve 402 is sealingly arranged on the oil return port 6013, and the two ends of the oil return pipe 401 are in communication with the oil return port 6013 and the hydraulic tank respectively; through such arrangement, after the device stops working, the hydraulic oil in the reinforcing rod 6 and the jaw structure 1 will flow back into the hydraulic tank through the oil return pipe 401; it is worth noting that the one-way valve 404 controls the flow direction of the hydraulic oil and limits the hydraulic oil to flow from the hydraulic tank to the jaw structure 1 through the oil inlet 108; and the switch valve 402 can release or lock the sealing relationship between the oil return pipe 401 and the sliding groove hole 6011.
