The embodiment of the application provides an environment-friendly road repairing and tamping device, which comprises a body 1 of a tamping machine and a frame body 2 for hand-holding, wherein a first connecting part 3 is fixedly connected to the body 1, a second connecting part 4 is fixedly connected to the frame body 2, and the first connecting part 3 is rotationally connected with the second connecting part 4.
Specifically, the body 1 of the tamper consists of a motor, a tamper head (an eccentric block and a vibrating body are arranged in the tamper head), a folding box, a lower tamper body and a tamper plate, the motor drives the eccentric block to rotate, the eccentric block enables the vibrating body to generate longitudinal exciting force, the exciting force is transmitted to the tamper plate through the lower tamper body, the tamper plate can jump up and down to form vibration compaction on a road surface, the first connecting part 3 and the second connecting part 4 are of block structures, the first connecting part 3 is respectively arranged at two ends of the body 1 in a certain radial direction, the number of the same second connecting parts 4 is also the same, the first connecting part 3 is rotationally connected with the second connecting part 4, such as through a bearing, the first connecting part 3 is fixedly connected with an outer ring of the bearing, the second connecting part 4 is fixedly connected with an inner ring of the bearing, as the vibration direction of the body 1 is mainly vertical, namely up and down vibration, the vibration force transmitted to the operator by the body 1 through the frame body 2 is basically vertical, so that the relative rotation between the first connecting part 3 and the second connecting part 4 is also vertical, wherein the frame body 2 is mainly used for protecting a motor and is used for being held by the operator, during operation, the body 1 vibrates up and down, the second connecting part 4 is driven by the first connecting part 3 to move up and down, the position of the frame body 2 held by the operator is the most far away from the first connecting part 3, the operator follows the moving direction of the body 1, one end of the frame body 2 close to the second connecting part 4 moves up and down, the other end rotates, namely the position of the frame body 2 at the position held by the operator is the rotation shaft in the hand of the operator, the frame body 2 is in a swinging posture in the process of vibrating and tamping the road surface by the body 1, so that the vibration force transmitted by the body 1 is used for the force required by swinging the frame body 2, so that the vibration transmitted to the operator is counteracted, and when the tamping direction of the body 1 needs to be adjusted, the operator can drive the body 1 to adjust the tamping direction by driving the frame body 2 to move.
The beneficial effects of this embodiment lie in: through rotating the connection between the first connecting part 3 and the second connecting part 4, then in the vibration process of the body 1 of the tamper, the frame body 2 is held by an operator, the frame body 2 takes the position of the operator holding part 21 as a swinging shaft to form swinging motion under the action of the vertical vibration force of the body 1, so that the vibration force of the body 1 forms the force required by the swinging of the frame body 2 in the process of being transmitted to the operator, and the vibration force cannot be transmitted to the body of the operator, so as to play a role in protecting the operator.
Further, the frame body 2 is divided into a protecting part 20 and a holding part 21, the protecting part 20 is fixedly connected with the second connecting part 4, and the holding part 21 is hinged with the protecting part 20.
Specifically, the protecting part 20 covers the outside of the motor, the tamper falls down in the transportation process or the operation process, the motor is not damaged, the surface temperature of the motor is high after the motor works for a long time, the protecting part 20 can avoid scalding of an operator, the handheld part 21 is a part which is held by the operator, the position of the part is far away from the motor and away from the tamper head, the handheld part 21 is hinged with the protecting part 20, when the protecting part 20 is driven to swing by the vibration of the body 1, the swinging shaft of the protecting part 20 can be the position where the handheld part 21 is hinged with the protecting part 20, then the handheld part 21 is not used as the swinging shaft to rotate on the palm of the operator, if one end of the handheld part 21, which is hinged with the protecting part 20, can be driven to swing up and down, the part which the handheld part 21 is contacted with the palm of the operator still rotates on the palm of the operator, but at the moment, the whole frame body 2 is equivalent to the swinging parts at two ends, the counteracting effect of the vibrating force of the body 1 is better, and the swinging amplitude of the handheld part 21 can be smaller, and the friction effect on the palm of the operator is reduced.
The vibration direction of the body 1 is mainly concentrated on the vertical direction, but the condition of tamping the road surface is complex, the vibration direction of the body 1 also has the condition of deviating from the vertical direction, so that the swing of the protecting part 20 is not up and down, the swing direction of the protecting part 20 is changed to inevitably drive the handheld part 21 to deflect, so that when the protecting part 20 swings, the influence on the handheld part 21 is increased, and in the embodiment, the hinging between the handheld part 21 and the protecting part 20 uses spherical hinge connection, the swing direction of the spherical hinge is more various, the handheld part 21 can adapt to the swing of the protecting part 20 in various directions, and the influence on the handheld part 21 caused by the swing of the protecting part 20 in any direction is basically not increased.
Still further, a jack 22 is formed on the protection portion 20, a slide bar 23 is slidably disposed in the jack 22, and the hand-held portion 21 is hinged with the slide bar 23 (the hand-held portion 21 is connected with the slide bar 23 through a spherical hinge); specifically, when the protecting portion 20 swings, the distance between the holding portion 21 and the body 1 is shortened, so that the swinging of the protecting portion 20 has a function of pulling forward or pushing backward on an operator through the holding portion 21, so that the operator cannot move along the body 1 more smoothly, therefore, in this embodiment, the protecting portion 20 is provided with the sliding rod 23 in a sliding manner, that is, when the protecting portion 20 swings, the body 1 has a pulling or pushing backward function on the protecting portion 20, and the operator has a reverse pulling or pushing function on the holding portion 21, so that a part of the sliding rod 23 slides out of the insert block 24 to compensate for the swinging of the protecting portion 20, and the shortened distance between the holding portion 21 and the body 1 is avoided, so that the swinging of the protecting portion 20 has a pulling forward or pushing backward function on the operator.
Preferably, an insert block 24 is fixedly connected to the hand-held portion 21, the insert block 24 is hinged to the slide bar 23, and when the insert block 24 is inserted into the insertion hole 22, the hand-held portion 21 and the protection portion 20 form a whole; specifically, in the foregoing embodiment, the hand-held portion 21 and the slide bar 23 are connected by the spherical hinge, because of the non-orientation of the spherical hinge, when the tamping moving direction of the body 1 needs to be adjusted, the non-orientation caused by the spherical hinge needs to be eliminated, so in this embodiment, when the operator pushes the hand-held portion 21 to drive the plug 24 to be plugged into the jack 22 on the protecting portion 20, the hand-held portion 21 and the protecting portion 20 can form a whole, in this process, the spherical hinge can follow into the jack 22, so that the tamping moving direction of the body 1 is convenient to be adjusted, when the tamping direction of the body 1 does not need to be adjusted, the operator pulls the hand-held portion 21 to drive the plug 24 to be separated from the jack 22, the spherical hinge also follows to extend out from the jack 22, and then the vibration generated during the tamping operation of the body 1 can be used again for swinging power up and down of the protecting portion 20.
Preferably, a locking mechanism 5 is disposed between the first connecting portion 3 and the second connecting portion 4, and when the plug 24 is completely plugged into the jack 22, the locking mechanism 5 limits the relative rotation between the first connecting portion 3 and the second connecting portion 4 based on the pushing force of the slide bar 23; specifically, the body 1 of the tamper is in the use, not only there is the demand of controlling adjustment tamp direction of movement, sometimes because by the unevenness on tamped road surface, the body 1 appears the condition of leaning forward or backward, still need adjust the position of body 1 around this moment, so avoid body 1 to empty, therefore when body 1 appears the anteversion or lean backward, need the operator through applying force to hand-held part 21 then drive body 1 get back to basic vertical direction's position, then in this embodiment, can be when the plug-in block 24 is pegged graft completely with jack 22 through promoting slide bar 23 and remove, slide bar 23 exerts force to locking mechanism 5, make locking mechanism 5 with the relative rotation between protection part 20 and the body 1 restricted, namely the relative rotation of first connecting portion 3 and second connecting portion 4 is restricted, because after plug-in block 24 and jack 22 are pegged graft, hand-held part 21 also forms an integral with protection part 20, then when operator lifts or presses down hand-held part 21, can drive back or the body 1 of leaning forward and the position of vertical direction is basic parallel (to main position 1) through pushing slide bar 23, can be to the plug-in block 23, make locking mechanism 5 draw back relative rotation between protection part 3 and the first connecting portion 3 and jack 4 and the second connecting portion 1 and the first connecting portion 3 and the second connecting portion 4 are kept away from, and the first connecting portion 3 and the second connecting portion is kept away from the first connecting portion 4 and the first connecting portion is more than the first connecting portion 3 and the second connecting portion is well.
The locking mechanism 5 includes a square groove 50 disposed on the first connecting portion 3, an annular body 51 is rotationally disposed in the square groove 50, in an initial state, an outer wall of the annular body 51 is in sliding contact with four side walls of the direction groove, the annular body 51 is made of elastic material, such as rubber, that is, the annular body 51 can rotate in the square groove 50 under the action of external force, four rotating shafts 52 are disposed in parallel along the circumferential direction of the annular body 51 on the second connecting portion 4, each rotating shaft 52 slides along the radial direction of the annular body 51 on the second connecting portion 4, that is, four sliding grooves are disposed on the second connecting portion 4, each rotating shaft 52 corresponds to one sliding groove, each rotating shaft 52 slides in the corresponding sliding groove, the sliding grooves are disposed along the radial direction of the annular body 51, in the initial position, each rotating shaft 52 is in sliding connection with the inner wall of the annular body 51, that is, the rotation of the annular body 51 is not hindered by the rotating shaft 52, a squeezing ring 53 is rotationally disposed on the second connecting portion 4, that is pushed by a sliding rod 59, and the sliding rod 59 is driven by the squeezing ring 53 to rotate; four extrusion grooves 54 are arranged in parallel in the circumferential direction of the extrusion ring 53, each extrusion groove 54 corresponds to one rotating shaft 52, and the four rotating shafts 52 are extruded by the four extrusion grooves 54 to expand outwards so that the annular body 51 is deformed into a square structure which is abutted against the side wall of the square groove 50.
When the first connecting portion 3 and the second connecting portion 4 do not need to be limited (i.e., the body 1 of the tamper does not have obvious forward tilting or backward tilting, in actual use of the tamper, the forward tilting or backward tilting is normal during the working process of the tamper because the road surface to be tamped is not completely flat, but the tilting angle of the tamper needs to be controlled within an allowable range, such as the forward tilting angle and the backward tilting angle range of-10 degrees, so that the road surface tamping can be normally performed), the insert block 24 is not inserted into the jack 22, the slide bar 23 does not push the swing rod 59 to move, the swing does not naturally drive the extrusion ring 53 to rotate, so that the extrusion groove 54 does not extrude the corresponding rotary shaft 52, the position of the rotary shaft 52 is unchanged, the ring body 51 is still in the ring structure, and the ring body 51 can rotate in the square groove 50.
When the first connecting portion 3 and the second connecting portion 4 need to be limited (i.e. the body 1 of the tamper has obvious forward tilting or backward tilting, the angle of the forward tilting or backward tilting exceeds the range from-10 degrees to 10 degrees, such as from-20 degrees to-10 degrees or from 10 degrees to 20 degrees, the position of the body 1 should be adjusted in time at this time to avoid tilting), the operator pushes the hand-held portion 21 to drive the insert 24 to be inserted into the insertion hole 22 on the protecting portion 20, the hand-held portion 21 can be integrated with the protecting portion 20, the insert 24 is pushed to move by the spherical hinge in the process of inserting the insert 22, the slide bar 23 is pushed to swing, the movement of the swing bar 59 drives the pressing ring 53 fixedly connected with the slide bar to rotate, the pressing ring 53 rotates to drive the pressing grooves 54 to rotate, each pressing groove 54 presses the rotating shaft 52 at the corresponding position, so that the four shafts 52 are pressed in a circular direction away from the pressing ring 53, so that the four shafts 52 expand the annular body 51 in four directions until the shafts 52 come into contact with the side walls of the square groove 50, and in the process, there occurs a case where the moving direction of the shafts 52 is not perfectly aligned with the corners of the square groove 50, the pressing ring 53 is difficult to be perfectly expanded into a square structure, so that during the insertion of the insert 24 into the insertion hole 22 (i.e., the insert 24 is already partially inserted into the insertion hole 22, at which time the hand-held portion 21 and the guard portion 20 are already formed as a whole, only the insert 24 is not completely inserted into the insertion hole 22), and it is also necessary for the operator to swing the hand-held portion 21 up and down to adjust the orientation of the shafts 52, so that when the shafts 52 expand the annular body 51, the shafts 52 move toward the corners of the square groove 50, so that when the shafts 52 come into contact with the corners adjacent side walls of the square groove 50, the annular body 51 is also expanded into a square configuration, the annular body 51 being unable to rotate within the square groove 50 to effect the restriction of the first and second connection portions 3, 4.
The extrusion groove 54 rotates along with the extrusion ring 53 to extrude the rotating shaft 52, so that the rotating shaft 52 moves towards a position far away from or near to the center of the extrusion ring 53, namely, if the extrusion ring 53 rotates clockwise, in an initial state, the position of the rotating shaft 52 in the extrusion groove 54 is near to the center of the extrusion ring 53, and the other end of the extrusion groove 54 is far away from the center of the extrusion ring 53, so that when the extrusion ring 53 rotates clockwise, the rotating shaft 52 is limited to move only radially along the extrusion ring 53, the extrusion groove 54 rotates clockwise to give the rotating shaft 52 a force far away from the center of the extrusion ring 53 in the radial direction, and thus the expansion action on the annular body 51 can be realized, otherwise, when the extrusion ring 53 rotates anticlockwise, the rotating shaft 52 rotates anticlockwise, the expansion force of the rotating shaft 52, which is close to the center of the extrusion ring 53 in the radial direction, is gradually reduced, and the annular body 51 gradually returns to the annular structure under the action of resilience force of the body itself.
As can be seen from the above, the annular body 51 has two states of an annular structure and a square structure, and the advantage of this arrangement is that when the annular body 51 is in the annular structure, the annular body 51 can rotate in the square groove 50, at this time, when the body 1 of the tamper vibrates, the protecting part 20 swings to counteract the vibration force, and the annular body 51 itself has elasticity, so during the vibration of the body 1, the first connecting part 3 and the second connecting part 4 are also not completely connected in a rotating manner, due to the annular body 51, an unoriented relative position can occur between the two parts due to the vibration, so that the effect of buffering the vibration force can be achieved (rotating connection, although relative rotation can occur after the two parts are stressed, interaction force still occurs between the two parts of the rotating connecting part, such as a bearing, and when the inner ring is subjected to upward force, the inner ring also has the force to the steel balls through the bearing, and although the rotation can counteract part of the outer ring, the inner ring still exerts part of the force to the outer ring through the steel balls); when the annular body 51 is in a square structure, the annular body 51 and the square groove 50 are fixedly connected, and the first connecting part 3 and the second connecting part 4 can be limited.
Further, each side wall of the square groove 50 is provided with a circular arc notch 55, and when the ring body 51 is not acted on by the four rotating shafts 52 to form a square structure, the outer wall of the ring body 51 is in sliding contact with the circular arc notch 55.
Specifically, each side wall of the square groove 50 is provided with a circular arc notch 55, so that the distance between two circular arc notches 55 at opposite positions is greater than the distance between the opposite side walls of the square groove 50, and thus the dimension of the annular body 51 is relatively large, while in the foregoing embodiment, when the annular body 51 is in an annular structure, the outer wall thereof is in sliding contact with the side wall of the square groove 50, and the side wall of the square groove 50 is in a tangential state with the outer wall of the annular body 51, the contact area between the two is too small, the restriction of the square groove 50 on the annular body 51 is small, after the annular body 51 is deformed, the situation that the positions deviate easily occurs in the square groove 50, namely, when the axis of the annular body 51 and the center of the square groove 50 are restored to the circular structure in the annular body 51, the situation that the restriction of the positions of the first connecting portion 3 and the second connecting portion 4 later causes adverse effects, in this embodiment, by providing the circular arc-shaped notch 55, the overall contact surface between the annular body 51 and the square groove 50 is greatly increased, so that the annular body 51 is difficult to deviate to other positions except at the rotating position in the square groove 50, and fatigue can occur after the annular body 51 is used for a long time.
Still further, each circular arc notch 55 on the first connecting portion 3 is provided with a circular arc groove 56, the circular arc groove 56 is divided into two extrusion sections 560 and a non-extrusion section 561 connecting the two extrusion sections 560, four sliding blocks 57 are arranged on the annular body 51, each sliding block 57 corresponds to one circular arc groove 56, and when the inclination angle of the body 1 is increased, the sliding blocks 57 enter the extrusion sections 560 from the non-extrusion sections 561.
Specifically, in the foregoing embodiment, the forward tilting or backward tilting is a normal phenomenon during the working process of the tamper, but the tilting angle thereof needs to be controlled within an allowable range, such as the forward tilting angle and the backward tilting angle range from-10 degrees to 10 degrees, so that the road surface tamping can be performed normally, and if the road surface tamping is performed at-20 degrees to-10 degrees or at 10 degrees to 20 degrees, the position of the body 1 should be adjusted in time to avoid the tilting of the body 1, in the prior art, the tilting angle of the body 1 is basically determined by the experience of the operator, and the operator is required to concentrate the spirit at all times, which increases the working difficulty of the operator undoubtedly, therefore in the present embodiment, by providing the circular arc-shaped groove 56 and dividing the circular arc-shaped groove 56 into two extrusion sections 560 and the non-extrusion section 561 connecting the two extrusion sections 560, the forward and backward swinging angles of the non-extrusion section 561 are between-10 degrees and 10 degrees, the forward and backward swinging angles of the two extrusion sections 560 are between-20 degrees and 20 degrees, namely, after the extrusion section 560 gives extrusion force to the sliding block 57 after the sliding block 57 enters the extrusion section 560, the relative rotation between the first connecting part 3 and the second connecting part 4 is obviously blocked, so that the vibration force of the body 1 drives the protection part 20 to swing smoothly, part of the vibration force is transmitted to the hand-held part 21 through the protection part 20, the hand-held part 21 is basically not felt by an operator, the operator can feel the force at the moment, the operator can push the hand-held part 21 to enable the plug block 24 to be plugged into the jack 22 according to the above, after a series of power transmission, the relative rotation between the first connecting part 3 and the second connecting part 4 is limited, to adjust the position of the body 1 to return to a position substantially parallel to the vertical direction from the forward or backward tilt.
Preferably, travel switches 58 are mounted at both ends of the arc track of the arc-shaped groove 56, and when the slide block 57 presses the travel switches 58, the body 1 is stopped; specifically, the situation of the road surface to be tamped by the tamper body 1 is complex in the working process, some unexpected situations are unavoidable, such as obvious unevenness occurs on the road surface, the attention of an operator is not concentrated, the tamper body 1 suddenly tilts, if the body 1 is still working at this time, the situation of hurting people is likely to occur, in this embodiment, the travel switch 58 is arranged at the end of the circular arc-shaped groove 56, and when the inclination angle of the body 1 exceeds the range from-20 degrees to 20 degrees, the slide block 57 can squeeze the travel switch 58, so that the body 1 is immediately stopped.
While certain exemplary embodiments of the present application have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope, the application being claimed.
