Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a brick transporting device for a brick paving machine. Background Art

[0002] During the use of the brick paving machine, it is first necessary to use the grabbing and transferring device to grab the bricks stacked in rows on the material table and transfer them to the brick conveyor belt, and then transport them one by one to the side close to the ground, so as to place the bricks one by one on the ground, and complete the dense arrangement of the bricks according to the preset laying method to complete the laying.

[0003] During the process of grabbing and transporting bricks, the gripping and transporting device's claws contact the bricks to be grabbed through the switch mechanism to acquire the grabbing signal; then, since the switch mechanism moves back and forth between the material table and the brick conveyor belt with the claws, the switch mechanism is easily triggered by mistake; since the operating intensity of the entire brick paving machine is relatively high, repeated false triggering can easily cause local deformation or even damage to the trigger mechanism of the switch device, and even cause damage to the switch device.

[0004] Therefore, it is necessary to improve the structure of the grabbing and transferring device to enhance the flexibility of the device when executing triggering actions and false triggering actions, so that even if false triggering activities occur during use, the triggering mechanism will not be damaged while ensuring the effective triggering of the grabbing action. Summary of the invention

[0009] The grab trigger switch includes a switch device body and a trigger mechanism; the switch device body includes a limit switch built into a protective shell; the contacts of the limit switch extend out of the protective shell through a window opened on the protective shell; the trigger mechanism includes a basic bracket and a trigger bracket; the basic bracket is vertically arranged, and its upper side is rotatably connected to the protective shell to trigger the limit switch by rotating in the trigger direction to collide with the contact; the top end of the trigger bracket is rotatably connected to the bottom end of the basic bracket, and a synchronization plate is provided at the rotational connection between the trigger bracket and the basic bracket; the synchronization plate is limited in the trigger direction of the trigger bracket, so that when the trigger bracket rotates in its trigger direction, the basic bracket is driven to rotate synchronously through the synchronization plate to trigger the limit switch, or the basic bracket remains stationary when the trigger bracket rotates in its mis-triggering direction.

[0010] Furthermore, the brick clamping mechanism also includes a controller, which is respectively connected to the first horizontal moving mechanism, the vertical moving mechanism, the second horizontal moving mechanism and the limit switch; wherein the controller controls the moving slider on the first horizontal moving mechanism to move back and forth between the material table and the first brick conveyor belt; the controller controls the lifting and lowering heights of the moving sliders on the two groups of vertical moving mechanisms to make the clamping grip adapt to the height position of the brick layer to be clamped, or to make the clamping grip descend to the position of the first brick conveyor belt; the controller controls the moving sliders on the two groups of second horizontal moving mechanisms to move toward or in the opposite direction to adjust the distance between the two clamping grips; the controller controls the stopping of the moving slider of the first horizontal moving mechanism on the material table side and the timing of the moving sliders of the two groups of second horizontal moving mechanisms to move toward each other through the limit switch, so that the two clamping grips are accurately clamped on the two end sides of the single row of brick groups.

[0011] Furthermore, a mounting block is fixed on the base bracket, on which a through hole is horizontally opened which is perpendicular to the protective shell and has a built-in bearing; a connecting shaft is vertically fixed on the protective shell, which passes through and is fixed in the bearing center hole of the mounting block, so that the base bracket is rotatably connected to the protective shell through the mounting block.

[0012] Furthermore, a vertical mounting through hole is provided on the base bracket along its length direction, so that the mounting block can be fixed at any position in the length direction of the base bracket through the mounting through hole.

[0013] Furthermore, a protective plate is provided on the protective shell, and the protective plate and the limit switch are arranged on both sides of the basic bracket respectively, so that when the basic bracket rotates in the direction of false triggering, the rotation is limited by the protective plate.

[0014] Furthermore, a reset mechanism is provided on the protective shell, which includes a tension spring and a fixed block; the fixed block is fixed to the rotation side of the basic bracket in the false triggering direction, one end of the tension spring is fixed to the basic bracket, and the other end is fixed to the fixed block, so that after the basic bracket rotates in the triggering direction, it is immediately restored to the vertical setting state through the tension spring.

[0015] Furthermore, the trigger bracket includes a fixed frame, a movable frame, an adjusting rod and a trigger part; wherein, the upper part of the fixed frame is rotatably connected to the bottom end of the basic frame so that it can rotate in the rotation direction of the basic frame; the movable frame is arranged in parallel and spaced relation with the lower part of the fixed frame, and its top is hingedly connected to the fixed frame so that it can swing in the rotation direction of the fixed frame; the adjusting rod is vertically arranged between the movable frame and the lower part of the fixed frame, one end of which is fixed on the fixed frame and the other end is passed through the movable frame; two limit blocks are arranged on the adjusting rods located on both sides of the movable frame, and the swing amplitude of the movable frame is adjusted by adjusting the position of the two limit blocks on the adjusting rods; the trigger part is connected to the bottom end of the movable frame.

[0017] Compared with the prior art, the brick transfer device for the brick paving machine has a reasonable structural design. The brick clamping mechanism cooperates with the grabbing trigger mechanism to realize the transfer of each row of bricks on the material table to the first brick conveyor belt. Among them, the grabbing trigger mechanism has a certain flexibility in structural design, so that it can not only send out grabbing signals in time during use, but also in the process of moving with the brick clamping mechanism, even if an erroneous triggering activity occurs, the trigger bracket can swing normally without triggering the limit switch, without affecting its own structure and without damaging the trigger mechanism and the switch device body.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention in any way.

[0025] The existing brick paving machine is used as a field brick paving equipment, which includes a material table 700 arranged on a movable chassis and multiple sets of brick conveying devices; see Figure 3 The multiple brick conveying devices on the brick paving machine include a brick transfer device, a first brick conveyor belt 900, a brick transfer conveyor device 901, a fixed conveyor device 902 and a second brick conveyor belt 903; wherein the brick transfer device is arranged adjacent to the material platform 700, and a plurality of brick layers are pre-stacked on the material platform 700, each brick layer is formed by a plurality of rows of brick groups stacked in rows, and the brick transfer device sequentially transfers the single-row brick groups 800 arranged on each row of the material platform 700 parallel to the first brick conveyor belt 900 to the first brick conveyor belt 900 by grabbing and transferring; the first brick conveyor belt 900 conveys the single-row brick groups 800 to one end close to the brick transfer conveyor device 901, and the brick transfer conveyor device 902 transfers the single-row brick groups 800 to the first brick conveyor belt 900 by grabbing and transferring. 01 Transfer each brick in the single-row brick group 800 one by one to the fixed conveying device 902 located under the first brick conveyor belt 900; at this time, the single-row brick group 800 initially arranged continuously on the brick transfer conveying device 901 is transformed into a single-row brick group 800 arranged with equal intervals on the fixed conveying device 902, and then transported to the second brick conveyor belt 903 through the fixed conveying device 902; the second brick conveyor belt 903 continues to transport each brick in the single-row brick group 800 arranged with equal intervals obliquely downward along the conveying direction of the fixed conveying device 902 to a height close to the ground, so that the bricks detached from the output end of the second brick conveyor belt 903 fall down and are laid on the specified position on the ground.

[0026] See also Figure 1 and Figure 2 The brick transfer device for the brick paving machine includes a brick clamping mechanism 500 and a grabbing trigger switch 600. During the clamping and transfer process of the single-row brick group 800 on the material table 700, not only can the grabbing trigger switch 600 be used to trigger the clamping action, but also the problem of false triggering of the grabbing trigger switch 600 by the clamping mechanism 500 during the transfer process can be avoided.

[0027] The brick clamping mechanism 500 includes a first horizontal moving mechanism 501, two groups of vertical moving mechanisms 502, two groups of second horizontal moving mechanisms 503 and two clamping grips 504; wherein the first horizontal moving mechanism 501 is horizontally spanned above the material platform 700 and the first brick conveyor belt 900 through a support beam fixed on a movable chassis; the two groups of vertical moving mechanisms 502 are symmetrically arranged in the conveying direction of the first brick conveyor belt 900, and the top ends of the two groups are respectively fixed on both sides of the bottom of the moving slider of the first horizontal moving mechanism 501, so that the two groups of vertical moving mechanisms 502 can be horizontally and synchronously moved from above the first brick conveyor belt 900 to the material platform 700. Above; a connecting beam 505 is horizontally connected and fixed between the moving sliders of the two groups of vertical moving mechanisms 502, and the two groups of second horizontal moving mechanisms 503 are symmetrically fixed at the bottom of the connecting beam 505, so that the two groups of second horizontal moving mechanisms 503 can be synchronously lifted and lowered in the vertical direction through the two groups of vertical moving mechanisms 502; the two clamping claws 504 are two vertical plates, which are symmetrically arranged in a parallel manner and respectively fixed on the bottom surfaces of the moving sliders of the two groups of second horizontal moving mechanisms 503, so as to adjust the distance between the two clamping claws 504 by controlling the moving blocks on the two groups of second horizontal moving mechanisms 503 to move toward each other synchronously or move in opposite directions synchronously.

[0028] In this embodiment, the first horizontal moving mechanism 501, the vertical moving mechanism 502, and the second horizontal moving mechanism 503 can all be assembled using existing devices with corresponding action functions, such as an electrically controlled moving slide; as another implementation of this embodiment, the second horizontal moving mechanism 503 and the two clamping claws 504 can also be replaced by parallel mechanical claws.

[0029] The brick clamping mechanism 500 also includes a controller, which is respectively connected to the first horizontal moving mechanism 501, the vertical moving mechanism 502 and the second horizontal moving mechanism 503 to control the brick clamping mechanism 500 to grab and transfer the multiple rows of brick groups 800 stacked on the material platform 700 one by one; specifically, since the table height of the material platform 700 is fixed, and the multiple rows of brick groups on the material platform 700 can also be arranged along the conveying direction of the first brick conveyor belt 900, that is, the height of each layer of bricks can be determined, but the distance from the brick clamping mechanism 500 is uncertain; therefore, the brick clamping mechanism 500 can first adjust the vertical moving distance of the moving slider on the vertical moving mechanism 502 through the controller in the vertical direction, and in the horizontal direction, the horizontal moving distance of the moving slider on the first horizontal moving mechanism 501 needs to be achieved through the grab trigger switch 600, that is, the grab trigger switch 600 is used to detect that the brick clamping mechanism 500 has reached the single row of brick groups 800, and a grab trigger switch 600 is issued. Signal, at this time, the controller controls the moving slider on the first horizontal moving mechanism 501 to stop moving, and controls the moving sliders on the two second horizontal moving mechanisms 503 to move synchronously toward each other, so that the two clamping claws 504 clamp on the brick side walls at both ends of the single-row brick group, to achieve the overall clamping of the single-row brick group 800; the controller controls the moving slider on the first horizontal moving mechanism 501 to move in the opposite direction to above the first brick conveyor belt 900, and then controls the moving slider of the vertical moving mechanism 502 to move downward, and controls the moving sliders on the two second horizontal moving mechanisms 503 to move in the opposite direction synchronously, so as to realize the lowering of the clamped single-row brick group 800 to the first brick conveyor belt 900, that is, to complete the transportation of the single-row brick group from the side of the material table 700 to the side of the first brick conveyor belt 900; and so on, the brick clamping mechanism 500 finally completes the transfer of the multi-layer single-row brick groups 800 stacked on the material table in a top-down order, and the transfer of the single-row brick groups 800 of each layer in a near-to-far order.

[0030] See also Figure 5 The grabbing trigger switch 600 includes a switch device body and a trigger mechanism; wherein the switch device body includes a limit switch 104 arranged in a protective shell 100, and the contact of the limit switch 104 extends out of the protective shell 100 through a window opened on the protective shell 100, so as to collide with the contact of the limit switch 104 through the trigger mechanism, so that the limit switch 104 transmits a grabbing signal to the controller connected thereto, and then the controller performs the above-mentioned grabbing and transporting action on the single-row brick group 800 based on the grabbing signal.

[0031] The trigger mechanism includes a base support 300 and a trigger support connected from top to bottom; wherein,

[0032] The basic bracket 300 is a vertically arranged frame, on which a mounting block 200 is fixed. A through hole perpendicular to the protective shell 100 and with a bearing built in is opened in the horizontal direction on the mounting block 200; correspondingly, a connecting shaft 103 is vertically fixed on the protective shell 100 located below the window, which is passed through and fixed in the bearing center hole of the mounting block 200, so that the basic bracket 300 is rotatably connected to the switch device body, that is, the basic bracket 300 can rotate clockwise or counterclockwise around the connecting shaft 103; the setting position of the basic bracket 300 on the switch device body is adapted to the setting position of the limit switch 104 on the switch device body, so that when the basic bracket 300 rotates counterclockwise, its top end collides with the contact of the limit switch 104 and transmits a grab signal, and when the basic bracket 300 rotates clockwise, the limit switch 104 will not be triggered.

[0033] As a preferred technical solution of this embodiment, a vertical mounting through hole 302 is provided on the base bracket 300 along its length direction, so that the mounting block 200 can be fixed at any position in the length direction of the base bracket 300, thereby adjusting the length of the base bracket 300 extending below the protective shell 100. In this embodiment, a strip-shaped mounting through hole 302 is provided on the base bracket 300 along its length direction; the mounting block 200 is composed of two fixing plates arranged in parallel and symmetrically arranged on the front and rear sides of the base bracket 300, and the upper sides of the two plates are provided with mounting through holes for assembling bearings, and the lower sides of the two plates are provided with screw holes for setting bolts, so that the two plates are clamped and fixed on the front and rear sides of the base bracket 300 by bolts, so as to be connected and fixed to the base bracket 300 as a whole; the mounting block 200 cooperates with the mounting through hole 302, so that the fixing position of the mounting block 200 on the base bracket 300 is adjustable, while reducing the difficulty of installation and facilitating adjustment.

[0034] A protective plate 101 is also provided on the protective shell 100, and the protective plate 101 and the limit switch 104 are respectively arranged on both sides of the top of the basic bracket 300 to limit the rotation of the basic bracket 300 to the side where the limit switch 104 is not provided; in this embodiment, since the contact of the limit switch 104 is arranged on the left side of the basic bracket 300, the counterclockwise rotation of the basic bracket 300 around the rotation axis 103 belongs to the switch triggering action, that is, the counterclockwise rotation direction of the basic bracket 300 is the triggering direction; on the contrary, the clockwise rotation of the basic bracket 300 around the rotation axis 103 belongs to the switch triggering action. The false triggering action, that is, the clockwise rotation direction of the basic bracket 300 is the false triggering direction; therefore, in order to limit the false triggering action, a protective plate 101 is arranged on the outer wall of the protective shell 100 located on the right side of the basic bracket 300; specifically, the protective plate 101 is vertically arranged on the adjacent side of the basic bracket 300 and vertically fixed on the outer wall of the protective shell, so that when the basic bracket 300 rotates clockwise around the rotation axis 103 due to external force, the protective plate 101 forms a limit on the basic bracket 300 to prevent the basic bracket 300 from rotating in the false triggering direction due to the external force.

[0035] The grab trigger switch 600 also includes a reset mechanism, which includes a tension spring 102 and a fixed block 105; specifically, the fixed block 105 is fixed on the protective housing 100 located on the right side of the basic bracket 300, and is spaced apart from the basic bracket 300; the front end surface of the fixed block 105 is preferably flush with the front end surface of the basic bracket 300, and the two ends of the tension spring 102 are respectively fixed on the front end surfaces of the basic bracket 300 and the fixed block 105. In the initial state, the tension spring 102 is set in a free state; in actual application, when the basic bracket 300 rotates counterclockwise to trigger the limit switch 104, the tension spring 102 is stretched synchronously; furthermore, after the swinging ends, the basic bracket 300 can rotate clockwise synchronously with the process of the tension spring 102 restoring the initial state, and reset to the initial vertical state, so as to wait for the execution of the next triggering activity action.

[0036] The trigger bracket is arranged below the base bracket 300, and its top end is rotatably connected to the bottom end of the base bracket 300, so that the trigger bracket can rotate clockwise or counterclockwise relative to the base bracket 300; a synchronization plate 301 that can limit the clockwise rotation of the trigger bracket is arranged at the rotation connection between the trigger bracket and the base bracket 300, so that the trigger bracket can actually only rotate clockwise relative to the base bracket 300; wherein, the clockwise rotation direction of the trigger bracket is its false triggering action direction, and the counterclockwise rotation direction of the trigger bracket is its triggering action direction.

[0037] In this embodiment, the synchronization plate 301 is composed of two vertical plates connected vertically, one of which is fixed to the back side of the bottom end of the basic bracket 300, so that the other vertical plate is limited to the right side of the top of the trigger bracket, so that when the trigger bracket is to rotate counterclockwise, the top of the trigger bracket cannot rotate because it is against the limited vertical plate; the setting of the synchronization plate 301 does not affect the rotation setting relationship between the trigger bracket and the basic bracket 300. Based on this, in actual application, when the bottom end of the trigger bracket is subjected to external force and rotates clockwise, the basic bracket 300 has no rotation action; and when the bottom end of the trigger bracket is subjected to external force and rotates counterclockwise, the trigger bracket can only use the rotation setting relationship between the basic bracket 300 and the protective shell 100 under the limiting action of the synchronization plate 301, and rotate counterclockwise synchronously with the basic bracket 300, that is, perform a trigger activity action.

[0038] In order to better meet the requirements of the actual switch triggering environment, the trigger bracket includes a fixed frame 401, a movable frame 402, an adjusting rod 403 and a triggering part 404; wherein, the upper part of the fixed frame 401 is rotatably connected to the bottom end of the basic frame 300, so that it can rotate clockwise or counterclockwise in the rotation direction of the basic frame 300; the movable frame 402 is arranged in parallel and spaced relation with the lower part of the fixed frame 401, and its top is hingedly connected to the fixed frame 401, so that it can swing back and forth in the rotation direction of the fixed frame 401; the adjusting rod 403 is vertically arranged between the movable frame 402 and the lower part of the fixed frame 401, one end of which is fixed on the fixed frame 401 and the other end is passed through the movable frame 402; the movable frame 402 is arranged at intervals on the adjusting rod 403, so that its swinging amplitude can be adjusted; the triggering part 404 is connected to the bottom end of the movable frame 402, which is used to contact with the brick, and then under the interaction between the brick and the triggering part 404, the trigger bracket is pushed to rotate.

[0039] Preferably, the trigger part 404 includes two rollers, which are symmetrically arranged on both sides of the bottom end of the movable frame 402 and can roll freely in the swing direction of the movable frame 402 to achieve sliding contact with objects such as bricks 500, thereby improving the structural flexibility of the trigger bracket and reducing the occurrence of false triggering.

[0040] In this embodiment, the fixing frame 401 is composed of an upper connecting plate and a lower connecting plate; the upper connecting plate is a right-angle plate, which is formed by connecting a vertical plate with a horizontal plate vertically fixed to the bottom end of the vertical plate; wherein the vertical plate of the upper connecting plate is arranged in parallel with a vertical plate of the synchronous plate 301, and is respectively arranged on the front and rear sides of the basic bracket 300, and a through hole with a built-in bearing is vertically opened in the upper direction of the vertical plate of the upper connecting plate, a rotating shaft is passed through and fixed in the shaft sleeve, and the rear end of the rotating shaft is vertically passed through and fixed to the vertical plate through the strip-shaped mounting through hole 302, so that the fixing frame 401 is rotatably connected to the basic bracket 300; the lower connecting plate is a The movable frame 402 is a vertical plate, which is connected from top to bottom by a vertical plate and an inclined plate, and its length is greater than the length of the lower connecting plate; the vertical plate and the lower connecting plate of the movable frame 402 are arranged in parallel and symmetrically arranged on the left and right sides of the bottom surface of the horizontal plate of the upper connecting plate, wherein a hinge 405 is arranged on the left top surface of the horizontal plate, one end of the hinge 405 is horizontally fixed to the horizontal plate by screws, and the other end is fixed to the top plate wall of the vertical plate of the movable frame 402, so that the vertical plate of the movable frame 402 is hingedly connected to the horizontal plate by the hinge 405, and can swing left and right relative to the fixed frame 401; on the upper edge of the vertical plate of the movable frame 402 A strip through hole is provided in the vertical direction, and a screw hole is provided in the lower connecting plate; the adjusting rod 403 is a cylindrical rod body, and external threads are processed on the rod walls at both ends, and a limiting cap is provided at one end of the rod body; one end of the adjusting rod 403 with the limiting cap is vertically penetrated and threadedly connected and fixed in the screw hole of the lower connecting plate, and the other end of the adjusting rod 403 is penetrated in the strip through hole on the movable frame 402, and the movable frame 402 can be movably limited on the adjusting rod 403 by two limiting blocks 406 which are sleeved on the end side of the adjusting rod 403 and located on both sides of the movable frame 402; by adjusting the two limiting blocks 406 on the adjusting rod 403 The position and spacing of the movable frame 402 are adjusted to limit the swing range of the movable frame 402, thereby improving the flexibility of the trigger bracket structure and realizing the adjustment of the sensitivity of the trigger part 404 to the trigger action; the angle between the inclined plate of the movable frame 402 and its vertical plate is an obtuse angle, and the inclined plate is arranged in a manner of obliquely toward the outside of the trigger bracket (that is, the left side of the vertical plate of the movable frame 402); wherein, the spacing between the bottom end of the trigger part 404 and the clamping grip 504 is adapted to the size of the brick, so that when the trigger part 404 abuts against the side wall of the brick, the clamping grip 504 should be centrally arranged on both ends of the single-row brick group 800 to ensure the stability of clamping.

[0041] See also Figure 1The grab trigger switch 600 is fixed on the brick clamping mechanism 500 through the switch device body, specifically, fixed on the side of the connecting beam 505 of the brick clamping mechanism 500 away from the material platform 700; in the process of the grab trigger switch 600 approaching the material platform 700 synchronously with the brick clamping mechanism 500, its trigger part 404 is used to abut the single-row brick group 800, triggering the grab trigger switch 600 to send a grab signal to the controller, thereby using the controller to control the brick clamping mechanism 500 to stop and grab the single-row brick group 800, and then transport it to the first brick conveyor belt 900.

[0042] In practical applications, the grab trigger switch 600 can perform the action of triggering the limit switch, and can also perform the action of avoiding the mistaken triggering of the limit switch, effectively ensuring the safety of the trigger mechanism, specifically:

[0043] See also Figure 5 In the process of grabbing the trigger switch 600 and moving with the brick clamping mechanism 500 toward the material platform 700, when the trigger part 404 abuts against the side wall of the single-row brick group 800 and continues to move with the brick clamping mechanism 500, the single-row brick group 800 will push the trigger part 404 to drive the trigger bracket to rotate counterclockwise. At this time, since the synchronous plate 301 is limited at the rotation connection between the trigger bracket and the basic bracket 300, the trigger bracket synchronously drives the basic bracket 300 to rotate counterclockwise until the basic bracket 300 collides with the contact of the limit switch 104; the limit switch 104 moves to the control The controller sends a grabbing signal, and the controller randomly controls the brick clamping mechanism 500 to stop moving, and controls the two clamping claws to move towards each other until they are clamped at both ends of the single-row brick group 800, and then the controller controls the brick clamping mechanism 500 to move in the opposite direction to above the first brick conveyor belt 900, and puts down the single-row brick group 800; during the reverse movement of the brick clamping mechanism 500, the base bracket 300 drives the trigger bracket to return to the initial vertical setting state under the action of the tension spring 102, and reduces the reset swing of the base bracket 300 under the limiting action of the protective plate 101;

[0044] See also Figure 6 In the process of grabbing the trigger switch 600 and moving it with the brick clamping mechanism 500 toward the first brick conveyor belt 900, or in the process of lowering the single-row brick group 800, when the trigger part 404 abuts against the top surface of the brick or the top side of other objects (such as a conveyor belt), the trigger part 404 will drive the trigger bracket to rotate clockwise. At this time, since the trigger bracket is rotationally connected to the base bracket 300, the base bracket 300 does not rotate synchronously with the trigger bracket, and still maintains a vertical setting state, effectively avoiding the base bracket 300 from being accidentally triggered and rotating, thereby preventing the limit switch from being damaged due to accidental triggering activities.

[0045] The above are only preferred implementation modes of the present invention. As long as the technical solutions of the present invention are achieved by substantially the same means, they are within the protection scope of the present invention.
