Description

Technical Field

[0001] This invention relates to the field of unloading hopper technology in coarse crushing workshops, and in particular to a forming device for unloading hoppers in coarse crushing workshops. Background Technology

[0002] The design of the discharge head in the coarse crushing workshop of a conventional sand-mixing system only considers the general reinforced concrete structure design, without adequately protecting the walls of the discharge hopper. This results in the concrete on the front and sides of the discharge hopper being damaged by the impact of boulders during the unloading process, thus adversely affecting the normal operation of the coarse crushing workshop.

[0003] To address this issue, we need to improve and optimize the design of the discharge hopper in the coarse crushing plant. Firstly, we can consider adding a protective material, such as wear-resistant steel plates or rubber linings, to the hopper walls to improve their wear resistance and impact resistance. This can effectively reduce the impact of aggregates on the concrete, thus protecting the hopper walls from damage. Secondly, we can consider adding buffer devices, such as rubber shock-absorbing pads or spring dampers, to the discharge hopper design to absorb the impact force generated when aggregates hit. This can mitigate the impact on the concrete and reduce the risk of damage.

[0004] However, existing wear-resistant steel plates, rubber liners, or buffer devices are installed or pasted onto the inner wall of the unloading hopper after the cement is poured and formed. Wear-resistant steel plates or buffer devices installed in this way will loosen or even fall off after long-term use, resulting in unstable use. Summary of the Invention

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a forming device for a discharge hopper in a coarse crushing workshop. The forming device includes a casting component 100, a protective plate component 200, and a support component 300. The casting component 100 is used to cast and form cement paste. The protective plate component 200 is used to form integrally with the cement paste and to protect the discharge hopper in normal use. The support component 300 is used to support the template component 101 during the casting process to prevent the template component 101 from tilting.

[0028] Specifically, the casting component 100 includes a template 101 and a steel frame (not shown in the figure). The template 101 has a casting space inside, and the steel frame is set inside the casting space. When in use, cement slurry is poured into the casting space. The protective plate assembly 200 is disposed within the pouring space. The protective plate assembly 200 includes an inner protective plate 201 and an outer protective plate 202, which are arranged parallel to each other. The inner protective plate 201 is tied to the steel frame by steel wire, and the outer protective plate 202 is elastically installed on the inner protective plate 201. The outer protective plate 202 is adapted to abut against the inner wall of the template 101. The support assembly 300 includes a support member 301 detachably installed on the outside of the template 101. During the pouring process, the support member 301 abuts against the outer wall of the template 101 on the side away from the outer protective plate 202. The support member 301 is used to support the template 101, thereby enabling the template 101 to remain stable during the pouring process and preventing deformation of the template 101.

[0029] In use, the template 101 is first placed in the predetermined position, and then the inner protective plate 201 and outer protective plate 202 of the protective plate assembly 200 are installed into the template 101 in sequence. Finally, the support assembly 300 is fixed to the ground. The support member 301 of the support assembly 300 abuts against the outer wall of the template 101 on the side away from the outer protective plate 202. During the pouring process, the support member 301 ensures the stability of the template 101 and prevents the template 101 from deforming.

[0030] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the inner protective plate 201 has an installation cavity 201a on the side facing the outer protective plate 202. The outer protective plate 202 is slidably installed in the installation cavity 201a. The outer protective plate can slide relative to the inner protective plate 201, that is, the outer protective plate 202 can move closer to or away from the inner protective plate 201 in the horizontal direction. During pouring, the inner protective plate 201 is fixed on the steel frame. At this time, the outer protective plate 202 is located between the inner protective plate 201 and the template 101. The outer protective plate and the template 101 are pressed together, thereby stabilizing the inner protective plate 201. After pouring is completed, the template 101 is removed. During the unloading process, the stones hit the outer protective plate 202. The outer protective plate 202 plays a buffering role under the action of elasticity, further enhancing the protection effect on the inner wall of the unloading hopper.

[0032] Preferably, the outer protective plate 202 has a sliding column 202a on the side facing the inner protective plate 201. Multiple sliding columns 202a are provided. The mounting cavity 201a has a limiting hole 201b on the side facing the outer protective plate 202. The sliding column 202a is slidably installed in the limiting hole 201b. A return spring 202b is sleeved on the sliding column 202a. The two ends of the return spring 202b abut against the outer protective plate 202 and the inner protective plate 201, respectively. The return spring 202b provides elastic force. During the pouring process, the return spring 202b makes the outer protective plate abut against the template 101, so that the inner protective plate 201 remains stable. After the pouring is completed, the outer protective plate 202 pops out from the inner protective plate 201 under the action of the return spring 202b. During the unloading process, the return spring 202b also makes the outer protective plate 202 able to buffer the stone.

[0033] Preferably, the inner protective plate 201 has a horizontally arranged first flow channel 202c on the side away from the outer protective plate 202. The first flow channel 202c is connected to the limiting hole 201b. The end of the sliding column 202a that extends into the limiting hole 201b is provided with a sealing column 202d. The sealing column 202d is slidably connected to the first flow channel 202c.

[0034] Furthermore, a vertically arranged second flow channel 201c is provided on the top of the inner protective plate 201, which is connected to the first flow channel 202c. A connecting pipe 201d is provided on the end face of the inner protective plate 201 away from the outer protective plate 202, and the central axis of the connecting pipe 201d coincides with the first flow channel 202c. A hook 201e is provided at the end of the connecting pipe 201d away from the outer protective plate 202. A third flow channel 201f is provided inside the connecting pipe 201d, which is arranged along the length of the connecting pipe 201d. One end of the third flow channel 201f passes through the hook 201e, and the other end of the third flow channel 201f is connected to the first flow channel 202c. The hook 201e is used to hook the steel frame, so that the inner protective plate 201 remains stable during the casting process. In the process, the return spring 202b keeps the outer protective plate 202 abutting against the template 101. At this time, the sealing column 202d blocks the connection between the second flow channel 201c and the first flow channel 202c, preventing cement slurry from leaking out of the second flow channel 201c. After pouring, the template 101 is removed, and the outer protective plate 202 pops out from the inner protective plate 201 under the action of the return spring 202b. At this time, the first flow channel 202c and the second flow channel 201c are connected. Water is then injected into the second flow channel 201c. Water is injected into the molded cement in sequence from the second flow channel 201c, the first flow channel 202c and the third flow channel 201f, keeping the cement moist and preventing it from cracking. During the unloading process, the return spring 202b also allows the outer protective plate 202 to buffer the stones.

[0035] Example 3 Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first and second embodiments.

[0036] Specifically, the support component 301 includes a support base 301a, a support plate 301b, and a connecting column 301c. The support base 301a is fixed to the ground by studs. The bottom of the support plate 301b is hinged to the left end of the support base 301a. The connecting column 301c is disposed between the support base 301a and the support plate 301b. The connecting column 301c is inclined. Both ends of the connecting column 301c are hinged to the support base 301a and the support plate 301b, respectively. When the support base 301a is installed in a suitable position, the support plate 301b abuts against the template component 101. The connecting column 301c is used to support the support plate 301b.

[0037] Preferably, strain gauges 301d are disposed on the support plate 301b. Two strain gauges 301d are disposed on the lower half and upper half of the support plate 301b, respectively. In this embodiment, the strain gauges 301d are disposed on the support plate 301b. During the process of pouring cement slurry into the pouring space, the strain gauges 301d are used to sense the pressure on the template 101. When the lateral force on the lower half of the template 101 is large due to the excessive pouring speed, the strain gauge 301d at this location transmits an electrical signal. When the pouring height reaches the predetermined height, the strain gauge 301d at this location transmits an electrical signal again and can also give a prompt signal to remind the construction personnel to stop pouring.

[0038] Furthermore, the support member 301 also includes a pressure-applying member 302 and a driving member 303. The driving member 303 is preferably a motor. The pressure-applying member 302 is slidably mounted on the support plate 301b. The driving member 303 is disposed on the connecting column 301c. The driving member 303 is electrically connected to the strain gauge 301d. The driving member 303 adjusts the forward, reverse, or stop working state according to the electrical signal transmitted by the strain gauge 301d. The driving member 303 drives the pressure-applying member 302 to slide on the support plate 301b according to the pressure value sensed by the strain gauge 301d, so that the pressure-applying member 302 can apply a lateral force to the appropriate position of the template member 101 to avoid deformation of the template member 101.

[0039] Specifically, a track 301b-1 is provided on the side end face of the support plate 301b facing the support base 301a. The track 301b-1 is vertically arranged, and the projection shape of the track 301b-1 on the vertical plane is arc-shaped, that is, the track 301b-1 bends towards the support plate 301b. There are two tracks 301b-1, which are arranged parallel to each other. The pressure member 302 has a slot, and the track 301b-1 is slidably connected to the slot. The pressure member 302 can slide along the contour direction of the track 301b-1, and the sliding path of the pressure member 302 is an arc.

[0040] Preferably, there are two connecting columns 301c, which are arranged parallel to each other. The upper and lower ends of the connecting columns 301c are hinged to the support plate 301b and the support base 301a, respectively. A fixing plate 301c-1 is provided between the two connecting columns 301c. The driving component 303 is set on the fixing plate 301c-1, and the length direction of the motor output shaft is perpendicular to the length direction of the connecting column 301c.

[0041] Preferably, the support member 301 further includes a rotating shaft 303a, which is disposed between two connecting columns 301c, and both ends of the rotating shaft 303a are rotatably connected to the two connecting columns 301c respectively. The rotating shaft 303a can rotate around its own central axis. The length direction of the rotating shaft 303a is parallel to the length direction of the output shaft of the drive member 303. The output shaft of the drive member 303 is provided with a first gear 303b, and the rotating shaft 303a is provided with a second gear 303c. The first gear 303b and the second gear 303c mesh. In use, the drive member 303 drives the rotating shaft 303a to rotate in sequence through the output shaft, the first gear 303b and the second gear 303c.

[0042] Furthermore, the support member 301 also includes a mounting post 302a. A retaining ring is provided at the right end of the mounting post 302a. The retaining ring is sleeved on the rotating shaft 303a and is keyed to the rotating shaft 303a. When the rotating shaft 303a rotates, it drives the mounting post 302a to rotate synchronously via the retaining ring. A mounting hole 302b is provided at the left end of the mounting post 302a. The central axis of the mounting hole 302b coincides with the central axis of the mounting post 302a. The device includes a first spring 302c and a movable post 302d on the side of the pressure member 302 facing the connecting post 301c. The movable post 302d is slidably installed in the mounting hole 302b and abuts against the first spring 302c. In this embodiment, the radius of the arc of the track 301b-1 is not constant, that is, the distance from the center of the fixed ring to the track 301b-1 is not constant. The distance from the center of the fixed ring to the track 301b-1 gradually decreases from the center of the track 301b-1 to both ends. When the mounting column 302a is in a horizontal position, the first spring 302c is in its initial state, meaning that the movable column 302d on the pressure member 302 neither compresses nor stretches the first spring 302c. When the pressure member 302 slides upward or downward along the direction of the track 301b-1, the mounting column 302a rotates accordingly, and the movable column 302d on the pressure member 302 compresses the first spring 302c. The elastic force of the first spring 302c always has the effect of forcing the pressure member 302 and the mounting column 302a to return to their original positions, that is, forcing the pressure member 302 and the mounting column 302a to maintain a horizontal state. At the same time, the first spring 302c also makes the pressure member 302 tend to compress the support plate 301b except in the horizontal position, thereby applying a lateral force to the template 101 and preventing the template 101 from deforming.

[0043] During the pouring process, strain gauges 301d installed on the lower and upper halves of the support plate 301b sense the pressure changes at corresponding positions. The strain gauges 301d then transmit the pressure signal to the motor. The motor drives the rotating shaft 303a to rotate through the output shaft, the first gear 303b, and the second gear 303c in sequence. The rotating shaft 303a drives the mounting column 302a, the movable column 302d, and the pressure-applying component 302 to rotate synchronously through the fixed ring. This causes the pressure-applying component 302 to slide up or down along the contour direction of the track 301b-1, thereby compressing the first spring 302c. The first spring 302c applies a lateral force to the template 101 through the pressure-applying component 302 to counteract the pressure at the corresponding position and prevent the template 101 from deforming.

[0044] Specifically, it also includes a locking component 304, which includes two discs 304a. The two discs 304a are fixedly mounted at both ends of the rotating shaft 303a. Four arc-shaped grooves are formed on the circumferential surface of the discs 304a, evenly distributed around the circumference of the discs 304a. A ratchet block 304c is elastically installed within each arc-shaped groove. A ratchet groove is provided on the connecting column 301c, and the ratchet block 304c is adapted to engage with the ratchet groove. When the motor drives the pressure-bearing component to rotate to a suitable position via the rotating shaft 303a, the motor can either be continuously energized to apply a torque to counteract the restoring force of the first spring 302c, or it can be turned off to protect the motor. However, the motor will not be subjected to any additional torque at this time. The torque resisting the reset force of the first spring 302c causes the first spring 302c to rapidly reset, thereby driving the rotating shaft 303a to rotate rapidly through the movable column 302d, the mounting column 302a, and the fixed ring in sequence. The rotating shaft 303a drives the disc 304a to rotate rapidly in sync. The ratchet block 304c installed on the disc 304a engages with the ratchet groove under the action of centrifugal force, thereby interrupting the rotation trend of the rotating shaft 303a and keeping the pressure member 302 in a fixed state. When unlocking, the output shaft of the motor rotates in the opposite direction, causing the ratchet block 304c to disengage from the ratchet groove. Then the ratchet block 304c is stored in the disc 304a. After that, the output shaft of the motor rotates in the opposite direction again, so that the position of the pressure member 302 can be adjusted again.

[0045] Preferably, the support plate 301b has four mounting slots 304e on the side facing the template 101. The mounting slots 304e are horizontally arranged and the four mounting slots 304e are evenly arranged on the support plate 301b along the vertical direction. A clamping block 304f is elastically installed in the mounting slot 304e. Under the action of external force, the clamping block 304f tends to move towards the template 101. The left end of the clamping block 304f is adapted to abut against the template 101, and the right end of the clamping block 304f is adapted to abut against the pressure applying member 302. The pressure applying member 302 pushes the clamping block 304f, so that the clamping block 304f presses against the template 101, thereby applying a lateral force to the template 101.

[0046] Preferably, the clamping block 304f includes a clamping part 304f-1 and a sliding part 304f-2. The sliding part 304f-2 is slidably installed in the mounting groove 304e. The sliding part 304f-2 is located on the side of the clamping part 304f-1 near the vertical inner wall of the mounting groove 304e. Four through holes 304g are provided on the vertical inner wall of the mounting groove 304e. The four through holes 304g are horizontally arranged, and each of the four through holes 304g corresponds to one of the four mounting grooves 304e. 304g is connected to the mounting groove 304e. The sliding part 304f-2 passes through the through hole 304g and is slidably connected to the through hole 304g. A second spring 304h is sleeved on the sliding part 304f-2. One end of the second spring 304h abuts against the pressing part 304f-1, and the other end of the second spring 304h abuts against the vertical inner wall of the mounting groove 304e. The second spring 304h has a tendency to drive the pressing part 304f-1 to be housed in the mounting groove 304e.

[0047] Furthermore, the clamping block 304f also includes a connecting part 304f-3, which is detachably connected to the sliding part 304f-2. When the pressure member 302 is in the initial horizontal position, the arc surface of the slot is smooth and without protrusions. The connecting part 304f-3 is adapted to abut against the pressure member 302. The side of the connecting part 304f-3 that abuts against the pressure member 302 is an arc surface. The curvature of this arc surface is consistent with the curvature of the arc surface of the slot. The pressure member 302 pushes the clamping part 304f-1 to press the template member 101 through the connecting part 304f-3 and the sliding part 304f-2.

[0048] In use, the pressure-applying component 302 adjusts its position adaptively via a motor, so that the pressure-applying component 302 moves to the part of the template component 101 with greater pressure. At this time, the pressure-applying component 302 applies a lateral force to the template component 101 at the corresponding position through the connecting part 304f-3, the sliding part 304f-2 and the pressing part 304f-1 of the pressing block 304f in sequence, thereby offsetting the pressure at this point and preventing the template component 101 from deforming.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
