Description

Technical Field

[0001] The present invention relates to the technical field of road construction equipment, and particularly relates to a resonant crusher for cement pavements. Background Art

[0002] The road surface resonant crusher is used for crushing old cement road surfaces. The principle of the resonant crusher is that an eccentric force is generated by an exciter. After amplitude modulation and frequency modulation through a resonant beam, the beam generates resonance, driving the crushing hammer head to generate high-frequency and low-amplitude vibrations, so that the vibration frequency of the hammer head reaches or approaches the natural frequency of the concrete panel. The resonant crushers are divided into two categories, namely offset beam crushers and center beam crushers.

[0003] For example, the patent with the application number CN202011425072.2 discloses a resonant crusher. The excitation beam is connected to the vehicle body through a support shaft, and a flexible support shaft sleeve is provided between the support shaft and the vehicle body. An exciter is provided at one end of the excitation beam, and the exciter is connected to the excitation motor through a universal shaft; the counterweight shaft of the excitation beam is connected to the counterweight beam through a counterweight rod. One end of the counterweight beam is connected to the vehicle body in a relatively rotatable manner, and a counterweight is provided at the other end. The counterweight beam is connected to the vehicle body through a lifting hydraulic cylinder to control the lifting of the hammer head of the excitation beam; taking the axis of the support shaft as the boundary, the length ratio of the first vibration side close to the hammer head to the second vibration side close to the exciter is 6.8 - 7, so that the natural frequency of the excitation beam is 50 - 55 Hz; the first vibration side is the distance from the end of the excitation beam close to the hammer head to the axis of the support shaft; the second vibration side is the distance from the axis of the support shaft to the axis of the exciter. The present invention can greatly extend the trouble-free working time of the resonant crusher. However, this crusher still has the following deficiencies: when this resonant crusher is in use, the connection method between the crusher beam and the hammer head is only simply locked and connected by a large number of bolts. The locking and fixing method is relatively single, the fixing effect is average, and because a large number of fixing bolts are used, when replacing the hammer head, it is necessary to repeat the steps of disassembling and installing the bolts multiple times, making the hammer head replacement work time-consuming and laborious. Summary of the Invention

[0004] In view of this, the present invention provides a resonant crusher for cement pavements, which has a fixed clamping mechanism. Through the setting of this mechanism, the hammer head is clamped and fixed to the beam, replacing the traditional bolt fixing, making the connection work between the beam and the hammer head more concise and time-saving.

[0005] The present invention provides a resonant crusher for cement pavements, which specifically includes: a vehicle body, on which a bearing seat is fixedly installed on the loading platform in the middle of the vehicle body; the resonant beam is installed on the bearing seat through a bearing; an exciter is arranged at the rear end of the resonant beam; a sleeve is sleeved at the front end of the resonant beam; a connecting body is fixedly installed at the bottom of the sleeve; and a resonant hammer head is fixedly installed at the bottom end of the connecting body.

[0006] Optionally, limiting bumps are fixedly installed on the left and right inner sides of the sleeve; insertion slots are formed in the inner side walls of the limiting bumps, and the insertion slots are rectangular structures; loading slots are formed in the upper and lower sides inside the insertion slots; a loading block is slidably installed inside the loading slot, and the loading block is a rectangular structure; a stress block is fixedly installed inside the loading block, and the stress block is trapezoidal in structure; one end of spring B is embedded and installed on the outer wall of the loading block, and the other end of spring B is embedded and installed on the outer side wall of the loading slot; a block B is fixedly installed on the outer wall of the loading block, and the block B is a rectangular structure; a slot B is formed in the outer side wall of the block B; insertion slots are formed in the upper and lower sides inside the sleeve.

[0007] Optionally, connecting rods are rotatably installed on the left and right sides of the support frame, and the other ends of the connecting rods are rotatably connected to the outer sides of the sliders; a travel block is slidably installed at the central position inside the main slot, and the travel block is connected to the support frame by bolts; insertion blocks are slidably installed on the upper and lower sides inside the main slot, and the insertion blocks are rectangular structures; inclined slots are formed in the inner side walls of the insertion blocks; the inclined slots are inclined structures; a trigger post is fixedly installed on the outer side of the travel block, and the trigger post is inside the inclined slot; a baffle is fixedly installed on the outer side of the travel block; one end of spring A is embedded and installed on the outer side of the baffle, and the other end of spring A is embedded and installed on the outer wall of the main slot.

[0008] Optionally, a main slot is formed at the front end inside the resonance girder, and the main slot is a rectangular structure; a control bolt is arranged at the front end of the resonance girder; slot A is formed on the left and right sides of the resonance girder; a block A is arranged inside the slot A, and the block A is a rectangular structure; guide slots are formed on the left and right sides inside the main slot; a slider is slidably installed inside the guide slot; a plug-in block is fixedly installed on the outer side of the slider, and the outer end of the plug-in block is trapezoidal in structure; a support frame is arranged at the rear end of the control bolt, and the support frame is inside the main slot.

[0009] Beneficial effects

[0010] For the resonance lithotripter according to the embodiments of the present invention, compared with the traditional lithotripter, the slider drives the plug-in block to move outwards, so that the plug-in block is inserted into the insertion slot, and a first clamping defense line is generated between the sleeve and the resonance girder.

[0011] In addition, when the plug-in block is inserted into the insertion slot, the trapezoidal structure of the outer end of the plug-in block cooperates with the trapezoidal structure of the stress block to push the loading block and the block B outwards, so that the block B is inserted into the slot A, and a second clamping defense line is generated between the sleeve and the resonance girder.

[0012] Moreover, when the clamping block B is inserted into the inside of the clamping groove A, the clamping block A will be inserted into the inside of the clamping groove B, so as to generate a third clamping defense line between the sleeve fixing member and the resonance beam, indirectly enhancing the connection reliability between the resonance hammer head and the resonance beam.

[0013] In addition, when the stroke block drives the trigger post to move backward, the trigger post will drive the insertion block to move outward by utilizing the characteristic that the inclined groove is an inclined structure, so that the insertion block is inserted into the inside of the insertion slot, generating a fourth clamping defense line between the sleeve fixing member and the resonance beam.

[0014] Furthermore, the present invention has multiple different clamping and fixing mechanisms. Through the multiple clamping and fixing mechanisms, multiple clamping protection mechanisms are formed to enhance the firmness between the sleeve fixing member and the resonance beam, making the resonance hammer head and the resonance beam have extremely high stability. And the present invention only needs to rotate one control bolt to directly or indirectly trigger multiple clamping and fixing mechanisms, thus making the installation and disassembly steps of the resonance hammer head extremely streamlined, simplifying the replacement work of the resonance hammer head. Compared with the traditional bolt locking and fixing method, this clamping and fixing method is more time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0043] Embodiment: Please refer to Figures 1 to 9:

[0044] The present invention provides a resonant crusher for cement pavements, comprising: a vehicle body 6, on which a bearing seat 1 is fixedly installed on the loading platform in the middle of the vehicle body 6; a resonant beam 2 is installed on the bearing seat 1 through a bearing; an exciter 3 is arranged at the rear end of the resonant beam 2; a sleeve 4 is sleeved at the front end of the resonant beam 2; a connecting body 5 is fixedly installed at the bottom of the sleeve 4; a resonant hammer head 501 is fixedly installed at the bottom end of the connecting body 5. By the operation of the exciter 3, the resonant beam 2 starts to vibrate, and the resonant beam 2 drives the resonant hammer head 501 to resonate, so as to crush the road surface with the resonant hammer head 501.

[0045] In addition, according to an embodiment of the present invention, as Figure 6 and Figure 7 shown, a main groove 201 is opened at the front end inside the resonant beam 2, and the main groove 201 is of a rectangular structure; a control bolt 202 is arranged at the front end of the resonant beam 2; clamping grooves A203 are opened on the left and right sides of the resonant beam 2; a clamping block A204 is arranged inside the clamping groove A203, and the clamping block A204 is of a rectangular structure; guide grooves 205 are opened on the left and right sides inside the main groove 201; a sliding block 206 is slidably installed inside the guide groove 205; a plugging block 207 is fixedly installed on the outer side of the sliding block 206, and the outer end of the plugging block 207 is of a trapezoidal structure; a support frame 208 is arranged at the rear end of the control bolt 202, and the support frame 208 is inside the main groove 201. By rotating the control bolt 202, it drives the support frame 208, a stroke block 2010 and one end of a connecting rod 209 to move backward, and the other end of the connecting rod 209 expands and supports the sliding block 206 outward, so that the sliding block 206 drives the plugging block 207 to insert outward into the inside of a plugging groove 402.

[0046] In another embodiment: the control bolt 202 can be replaced by an electric rod, so that the electric rod completes the triggering work of the clamping mechanism, which is more time-saving and labor-saving compared with manually driving the control bolt 202 by hand.

[0047] In addition, according to an embodiment of the present invention, as Figure 8 and Figure 9As shown, link rods 209 are rotatably installed on the left and right sides of the support frame 208, and the other ends of the link rods 209 are rotatably connected to the outer sides of the sliders 206; a travel block 2010 is slidably installed at the central position inside the main groove 201, and the travel block 2010 is connected to the support frame 208 by bolts; insertion blocks 2012 are slidably installed on the upper and lower sides inside the main groove 201, and the insertion blocks 2012 are of rectangular structure; inclined grooves 2013 are formed on the inner side walls of the insertion blocks 2012; the inclined grooves 2013 are of inclined structure; a trigger post 2011 is fixedly installed on the outer side of the travel block 2010, and the trigger post 2011 is located inside the inclined groove 2013; a baffle 2014 is fixedly installed on the outer side of the travel block 2010; one end of a spring A 2015 is embedded on the outer side of the baffle 2014, and the other end of the spring A 2015 is embedded on the outer wall of the main groove 201. When the travel block 2010 moves backward, it will drive the trigger post 2011 to move backward, causing the trigger post 2011 to slide along the inclined groove 2013, so that the trigger post 2011 drives the insertion block 2012 to move outward under the action of the inclined structure of the inclined groove 2013, and the insertion block 2012 is inserted into the inside of the insertion slot 409.

[0048] In addition, according to the embodiments of the present invention, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, limiting bumps 401 are fixedly installed on the left and right sides inside the sleeve 4; insertion slots 402 are formed on the inner side walls of the limiting bumps 401, and the insertion slots 402 are of rectangular structure; load grooves 403 are formed on the upper and lower sides inside the insertion slots 402; load blocks 404 are slidably installed inside the load grooves 403, and the load blocks 404 are of rectangular structure; a force-bearing block 405 is fixedly installed on the inner side of the load block 404, and the force-bearing block 405 is of trapezoidal structure; one end of a spring B 406 is embedded on the outer wall of the load block 404, and the other end of the spring B 406 is embedded on the outer side wall of the load groove 403; a block B 407 is fixedly installed on the outer wall of the load block 404, and the block B 407 is of rectangular structure; a slot B 408 is formed on the outer side wall of the block B 407; insertion slots 409 are formed on the upper and lower sides inside the sleeve 4. When the insertion block 207 is inserted into the inside of the insertion slot 402, the insertion block 207 uses the trapezoidal structure at its outer end to push the force-bearing block 405 and the load block 404 outward, so that the load block 404 drives the block B 407 to move outward and insert into the inside of the slot A 203, and the block A 204 is synchronously inserted into the inside of the slot B 408.

[0049] Specific usage method and function of this embodiment: During use, first, the sleeve fixing member 4 is sleeved at a suitable position on the resonance girder 2. Then, rotate the control bolt 202 to drive one end of the support frame 208, the stroke block 2010, and the connecting rod 209 to move backward, causing the other end of the connecting rod 209 to expand and support the slider 206 outward, so that the slider 206 drives the plug-in block 207 to insert outward into the inside of the plug-in slot 402. When the plug-in block 207 inserts into the inside of the plug-in slot 402, the plug-in block 207 uses the trapezoidal structure at its outer end to push the force-bearing block 405 and the load block 404 outward, causing the load block 404 to drive the block B 407 to move outward and insert into the inside of the slot A 203, and the block A 204 to synchronously insert into the inside of the slot B 408. At the same time, the stroke block 2010 drives the trigger post 2011 to move backward, causing the trigger post 2011 to slide along the inclined slot 2013. Thus, under the action of the inclined structure of the inclined slot 2013, the trigger post 2011 drives the plug 2012 to move outward, and the plug 2012 is inserted into the inside of the slot 409. Thus, the fixed connection between the sleeve fixing member 4 and the resonance girder 2 is completed. Finally, the vehicle body 6 moves along the road surface to be broken. During the movement, the resonance girder 2 starts to vibrate by the operation of the vibrator 3, causing the resonance girder 2 to drive the resonance hammer head 501 to resonate, so that the resonance hammer head 501 crushes the road surface.

[0050] Finally, it should be noted that when the present invention describes the positions of various components and their cooperation relationships, etc., usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.

[0051] The above are only exemplary embodiments of the present invention and are not used to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
