Description

Technical Field

[0001] The invention relates to the technical field of curbstone installation, and in particular to a trolley for transporting and installing curbstones. Background Art

[0002] Curbstones are generally required between the dividing strip and the road surface, and between the sidewalk and the road surface of urban roads. Curbstones are often required at the edge of the central dividing strip of the highway, the right edge of the lane or the outer edge of the shoulder.

[0003] When installing existing curbstones, a trolley is used. The trolley has a lifting mechanism and a loading platform. During installation, the trolley is moved to the vicinity of the installation position, and the curbstone on the loading platform is lifted to the installation position by the lifting mechanism. However, after the existing trolley lifts the stone to the installation position, the position of the stone needs to be adjusted manually to ensure that the facades of several stones installed along the road remain flush. However, in actual construction projects, a section of road may require tens of thousands of curbstones. The installation method using the above-mentioned trolley and manual labor is time-consuming and has low construction efficiency. Summary of the invention

[0004] The present invention provides a trolley for transporting and installing curbstones, which can overcome the defects of the trolley and manual installation methods in the prior art that they are time-consuming and have low construction efficiency.

[0005] According to the present invention, a trolley for transporting and installing curbstones comprises a vehicle body, a hoisting module and an auxiliary module; the vehicle body is provided with a loading platform for loading stones; the hoisting module is used to hoist the stones to the installation position; The auxiliary module includes a support seat for being placed at the installation position; the support seat is provided with a receiving opening which runs through both sides and is arranged along the installation direction of the stone; the support seat is provided with a guiding mechanism; the guiding mechanism includes a limiting plate and an adjusting member located at the receiving opening; the limiting plate is provided with a receiving area which can receive the stone; the adjusting member is used to adjust the size of the receiving area so that the receiving area can keep matching with the stone.

[0006] Through the setting of the auxiliary module of the present invention and the guiding mechanism therein, when installing stones, after the first stone is installed to the accurate position, the support seat can be set above the positioned stone, and the side of the stone close to the installation direction can be placed between the two limit plates, and the distance between the two limit plates, that is, the size of the accommodating interval, can be adjusted by the adjusting member, so that the two limit plates are respectively fitted with the two vertical surfaces of the stone, and when hoisting the stone to be installed, it can be directly extended into the accommodating interval. At this time, the two vertical surfaces of the stone extended into the accommodating interval can be kept flush with the two vertical surfaces of the positioned stone, and there is no need to observe and manually adjust the position of subsequent stones, so that the stone can be positioned by extending into the accommodating interval, thereby reducing the installation time and improving the construction efficiency; before installing the next stone, the support seat is set above the last positioned stone, so that the next stone can be hoisted and the installation can continue.

[0007] Preferably, the accommodating opening passes through both sides of the support seat and one end close to the ground at the same time; the adjusting member includes a movable seat located in the accommodating opening; an end face of the movable seat close to the ground is provided with a sliding cavity along a direction perpendicular to the length of the accommodating opening; two sliders are slidably fitted in the sliding cavity; a bidirectional screw is rotatably fitted in the sliding cavity, and the two sections of the thread of the bidirectional screw are respectively fitted with the threads of the two sliders; the two ends of the bidirectional screw respectively pass through both sides of the movable seat and are respectively detachably connected with a rotating rod; second through-openings for the rotating rod to pass through are provided on both sides of the support seat away from the accommodating opening; the second through-openings are arranged in a direction perpendicular to the road surface; the limiting plate includes a vertical plate and a guide plate; the vertical plate is connected to the slider and remains perpendicular to the ground; one side of the vertical plate extends out of the accommodating opening and is connected to the guide plate; the two vertical plates remain parallel, and the two guide plates form an eight-shaped shape; the accommodating interval is formed between the two vertical plates and the two guide plates.

[0008] In the present invention, by setting a bidirectional screw, when the rotating rod is rotated, the bidirectional screw can be driven to rotate to drive the two limit plates to move relative to or away from each other, so as to realize the size adjustment of the accommodating interval; wherein the second through-hole can limit the movable seat from leaving the accommodating opening, and the width of the second through-hole is greater than the diameter of the rotating rod, so that the movable seat can move in multiple directions, and prevent the support seat from driving the limit plate to move, that is, the stone to move when an offset occurs, so as to prevent the installed stone from being offset due to the movement of the support seat; wherein the opening of the accommodating interval is made larger by setting a guide plate, so that the curb stone to be hoisted can be guided into the accommodating interval.

[0009] Preferably, the movable seat is vertically connected to a limiting height screw at one end face away from the sliding cavity; a first through-hole for the limiting height screw to pass through is provided at one end of the supporting seat away from the accommodating opening; the first through-hole is arranged in a direction perpendicular to the installation direction; the thread on the limiting height screw is matched with a knob that is tightly pressed against the end face of the supporting seat.

[0010] In the present invention, by setting the height limiting screw and the knob, the entire guide mechanism will not fall under the limit of the knob, so that the height can still be maintained when the moving seat is separated from the surface of the stone, and the moving seat can be made to fit tightly against the upper wall of the accommodating opening through the knob during transportation to prevent shaking during transportation.

[0011] Preferably, a distance mechanism is provided at the support seat; the distance mechanism includes a fixed seat, which is connected to an end face of the support seat away from the road surface and close to the side of the guide plate; the fixed seat is arranged in a direction perpendicular to the ground; the fixed seat is provided with a lifting opening that passes through both ends and both sides of the fixed seat; the lifting opening also passes through one end of the support seat and is connected to the accommodating opening; the lifting opening is provided with a lifting seat that slides along the length direction of the lifting opening; one side of the lifting seat is connected to a distance plate that can extend between the two vertical plates; one side of the fixed seat is threaded with a first positioning bolt that can be tightly pressed against the lifting seat.

[0012] In the present invention, by setting the distance mechanism, the distance plate that can be raised and lowered and can be positioned at a height by the first positioning bolt can be attached to the side wall of the stone that has been positioned and installed. The thickness of the distance plate is the size of the gap between the stones. After the distance plate is attached to the stone that has been positioned and installed, the stone that subsequently enters the accommodating interval can be attached to the other side of the positioning plate. At this time, the distance plate is clamped between the two stones, and the gap between the two stones has been reserved; so when the distance mechanism cooperates with the guide mechanism, after the stone to be installed enters the accommodating interval and is attached to the distance plate, the facades of all the stones are automatically kept flush, and the size of the gaps and spacings have been automatically reserved, so that the installation of the stones can be completed more quickly, further improving the construction efficiency.

[0013] Preferably, the distance plate is composed of a plurality of sub-plates connected end to end; the thickness of the plurality of sub-plates is arranged to increase from one end to the other end of the distance plate, and the sub-plate with the smallest thickness is arranged close to the vertical plate.

[0014] In the present invention, the distance plate is composed of several sub-plates of different thicknesses, so that the operator can place sub-plates of different thicknesses between two stones, so that the distance plate can adjust the gap spacing between the two stones. Generally speaking, hard curbstones such as granite and marble are suitable for using a smaller gap width, generally selected at about 3 mm; while the gap of soft curbstones such as sandstone and limestone should be maintained at more than 5 mm; therefore, the distance plate can adapt to the installation of curbstones of different materials and requirements; the thickness of several sub-plates can be increased by 1 mm.

[0015] Preferably, a guide rod is provided at the end face of the support seat along the length direction of the fixed seat; a guide ring is provided on one side of the lifting seat and extends to the outside of the lifting port; the guide ring is slidably matched with the guide rod, and a spring sleeved with the guide rod is pressed between the support seat and the guide ring.

[0016] In the present invention, by setting the guide ring, the guide rod and the spring, when the distance plate is not clamped between two stones, the spring can support the guide ring so that the distance plate always remains in a raised state, and when the distance plate is used to extend into the accommodating interval, the guide ring will compress the spring so that the distance plate always maintains a force to lift it away from the accommodating interval; therefore, there are two options for operating the distance plate, one is to continuously press the distance plate with the hand, and it will automatically rise after being released; the other is to position and release its height by the first positioning bolt.

[0017] Preferably, one end of the vertical plate away from the road surface is kept flush with the end of the moving seat close to the road surface; a calibration mechanism is provided on the vertical plate; the calibration mechanism includes a limit block; the limit block is fixed on one side of the vertical plate close to the inner wall of the support seat; the limit plate is hinged with a calibration plate that is perpendicular to the vertical plate; the calibration plate can be flipped 180°, and both sides can be kept flush with one end surface of the vertical plate close to the moving seat; the distance adjustment plate can be moved between the two calibration plates.

[0018] In the present invention, by setting the calibration plate, after the two stones are guided and spaced to complete the flushing of the facades and the reservation of the gap, the heights of the two stones can be conveniently calibrated through the calibration plate. Since one side of the calibration plate is flush with the end faces of the movable seat and the vertical plate, the top surface of the stone that has completed the positioning and installation of the former will be in contact with and remain flush with the end face of the movable seat, and one side of the calibration plate will be in contact with the top surface of the stone that has completed the positioning and installation of the former, and at the same time be located above the stone that has been positioned and installed in the latter. Therefore, by observing the state of the calibration plate, it can be known whether the height of the stone installed in the latter is kept flush with the height of the stone that has been positioned and installed in the former. If the latter is higher, the calibration plate will not be in contact with the end face of the vertical plate and will be tilted. If the latter is lower, there will be a gap between the calibration plate and the latter stone, thereby realizing auxiliary calibration of the height.

[0019] Preferably, a connecting mechanism cooperating with the vehicle body is provided at the support seat; the connecting mechanism includes a connecting plate and a sliding seat; a guide rail arranged along the length direction of the vehicle body and used for the sliding seat to slide and cooperate is provided at one side of the vehicle body; a second hinged seat is provided at one side of the sliding seat; a first hinged seat is provided at one side of the support seat; the first hinged seat and the second hinged seat are jointly hinged with a connecting plate.

[0020] In the present invention, the auxiliary module can slide on one side of the vehicle body through the setting of the connecting mechanism. It should be noted that the side of the vehicle body will not remain precisely parallel to the facade of the curb, regardless of whether it is manually driven or automatically driven. Therefore, the width of the second through-hole in the above text is greater than the setting of the rotating rod. When the vehicle body is offset, it will only drive the support seat and the structure connected to the support seat to move, and the guide mechanism will still be clamped at the stone, thereby not causing an offset effect on the installation of the curb. Therefore, connecting the auxiliary module to the vehicle body through the connecting mechanism can allow the auxiliary module to move with the vehicle without affecting the installation of the curb.

[0021] Preferably, the connecting plate includes a sleeve plate and an insert plate; a second rotating shaft hinged to the first hinge seat is provided at one end of the sleeve plate; a first rotating shaft hinged to the second hinge seat is provided at one end of the insert plate; a slot for the insert plate to be inserted into is provided at one end of the sleeve plate; a threaded barrel passing through the slot is provided at one side of the sleeve plate; a second positioning bolt capable of being tightly pressed against the insert plate is threadedly engaged with the threaded barrel; a plurality of first positioning grooves arranged at intervals and used for the second positioning bolt to be inserted into are provided at one side of the insert plate; a positioning block extending to one end of the first rotating shaft is provided; second positioning grooves distributed circumferentially are provided at the side wall of the positioning block; a positioning screw threadedly engaged with any second positioning groove is provided at the sliding seat.

[0022] In the present invention, by setting the connecting plate structure, the sleeve plate and the plug plate can be separated after the second positioning bolt is loosened or removed, so as to separate the auxiliary module from the vehicle body, and the insertion depth of the sleeve plate and the plug plate can be used to maintain different distances between the auxiliary module and the vehicle body; for example, after the installation is completed, the entire auxiliary module can be lifted and carried to the vehicle body by adjusting the insertion depth of the sleeve plate and the plug plate, and by the cooperation of the second positioning bolt and the first positioning groove, and the cooperation of the positioning screw and the second positioning groove, and the above-mentioned structure can be used to limit it to prevent it from falling; after the curb is installed, it can be directly loaded and taken away; there is no need to consider where to place it and limit it.

[0023] Preferably, the lifting module includes a turntable rotatably engaged with the vehicle body; a first motor for driving the turntable to rotate is provided on the vehicle body; a moving arm extending to the top of the loading platform is provided on the turntable; a moving cavity arranged along the length direction of the moving arm is provided on the moving arm; a driving screw rotatably engaged along the length direction of the moving cavity is provided inside the moving cavity, and a second motor for driving the driving screw to rotate; a moving block is threadedly engaged with the driving screw; a hydraulic cylinder and a third motor for driving the hydraulic cylinder to rotate are connected to the moving block; a clamp for clamping stones is connected to the piston rod of the hydraulic cylinder.

[0024] In the present invention, through the setting of the lifting module, the first motor can drive the turntable to rotate, so as to drive the moving arm to move in the horizontal direction along the axis of the turntable. The second motor can drive the moving block, the hydraulic cylinder and the clamp to move in the horizontal square along the radial direction of the turntable. The first motor and the second motor cooperate to enable the clamp to lift stones at any position in the horizontal direction. The third motor can drive the clamp to rotate so that the clamped stone can be turned around on the spot. The height of the clamp can be raised and lowered by the hydraulic cylinder to cooperate with the above structure to realize the lifting of the stone. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] By means of the auxiliary module 120 and the guide mechanism 222 therein in the present embodiment, when installing the stone 130, after the first stone 130 is installed to the accurate position, the support seat 221 can be erected above the positioned stone 130, and the side of the stone 130 close to the installation direction can be placed between the two limiting plates 3222, and the distance between the two limiting plates 3222, i.e. the size of the accommodating interval 3223, can be adjusted by the adjusting member 3221, so that the two limiting plates 3222 are respectively fitted with the two vertical surfaces of the stone 130, and when hoisting the stone 130 to be installed, it can be directly extended into the accommodating interval 3223, at this time, the two vertical surfaces of the stone 130 extended into the accommodating interval 3223 can be kept flush with the two vertical surfaces of the positioned stone 130, and there is no need to observe and manually adjust the position of the subsequent stone 130, so that the stone 130 can be positioned by extending into the accommodating interval 3223; in addition, the setting of the spacing mechanism 223 makes it possible to lift and lower the stone 130 The distance plate 82374232 which can be positioned by the first positioning bolt 6236 can be fitted on the side wall of the stone 130 which has been positioned and installed. The thickness of the distance plate 82374232 is the size of the gap between the stones 130. After the distance plate 82374232 is fitted on the stone 130 which has been positioned and installed, the stone 130 which subsequently enters the accommodating interval 3223 can fit on the other side of the positioning plate. 2 is sandwiched between two stones 130, and the gap between the two stones 130 has been reserved; therefore, when the distance mechanism 223 cooperates with the guide mechanism 222, after the stone 130 to be installed enters the accommodating area 3223 and fits with the distance plate 82374232, the facades of all the stones 130 are automatically kept flush, and the size of the gap and the spacing have been automatically reserved, so that the installation of the stone 130 can be completed more quickly, further improving the construction efficiency; in Figure 3 The figure shows that a stone 130 has been positioned and installed at the installation position on the roadside, and then the auxiliary module 120 is placed, and the distance plate 82374232 is attached to it to make it enter the accommodation interval 3223, waiting for the next stone 130 to be installed to enter the accommodation interval 3223; Figure 4 Shown is Figure 3The subsequent state of the state, i.e., the state in which the stone 130 to be installed enters the accommodation interval 3223; Figure 2 Shown is Figure 4 The subsequent state of the state, that is, the stone 130 being installed has been aligned with the facade and the gap has been reserved by the guide mechanism 222 and the distance mechanism 223. The next step is to compare the stone 130 being installed with the stone 130 that has been positioned and installed through the calibration mechanism 224 to assist in calibrating the height, that is, Figure 5 Status shown.

[0030] In this embodiment, the accommodating opening 2210 simultaneously passes through both sides of the support seat 221 and one end close to the ground; the adjusting member 3221 includes a movable seat 3220 located in the accommodating opening 2210; an end surface of the movable seat 3220 close to the ground is provided with a sliding cavity 72200 along a length direction perpendicular to the accommodating opening 2210; two sliders 72210 are slidably matched at the sliding cavity 72200; a bidirectional screw 72211 is rotatably matched at the sliding cavity 72200, and two sections of the thread of the bidirectional screw 72211 are respectively matched with the threads of the two sliders 72210; the two ends of the bidirectional screw 72211 respectively pass through both sides of the movable seat 3220, and are respectively detachably connected There is a rotating rod 72212; second through-holes 6212 for the rotating rod 72212 to pass through are provided on both sides of the support seat 221 away from the accommodating opening 2210; the second through-holes 6212 are arranged in a direction perpendicular to the road surface; the limiting plate 3222 includes a vertical plate 32220 and a guide plate 32221; the vertical plate 32220 is connected to the slider 72210 and remains perpendicular to the ground; one side of the vertical plate 32220 extends out of the accommodating opening 2210 and is connected to the guide plate 32221; the two vertical plates 32220 remain parallel, and the two guide plates 32221 form an eight-shaped shape; the accommodating interval 3223 is formed between the two vertical plates 32220 and the two guide plates 32221.

[0031] By setting the bidirectional screw 72211 in this embodiment, when the rotating rod 72212 is rotated, the bidirectional screw 72211 can be driven to rotate to drive the two limit plates 3222 to move relative to or away from each other, so as to achieve the size adjustment of the accommodating interval 3223; wherein the second through-hole 6212 can limit the movable seat 3220 from separating from the accommodating opening 2210, and the width of the second through-hole 6212 is greater than the diameter of the rotating rod 72212, so that the movable seat 3220 can move in multiple directions, preventing the support seat 221 from driving the limit plate 3222 to move, that is, the stone 130 to move when the support seat 221 is offset, so as to prevent the installed stone 130 from being offset due to the movement of the support seat 221; wherein the setting of the guide plate 32221 makes the opening of the accommodating interval 3223 larger, so that the curb stone 130 to be hoisted can be guided into the accommodating interval 3223.

[0032] In this embodiment, the movable seat 3220 is vertically connected to the limiting height screw 6224 at one end face away from the sliding cavity 72200; a first through-hole 6211 for the limiting height screw 6224 to pass through is provided at one end of the support seat 221 away from the accommodating opening 2210; the first through-hole 6211 is arranged in a direction perpendicular to the installation direction; the threaded part of the limiting height screw 6224 is matched with a knob 6225 which is tightly pressed against the end face of the support seat 221.

[0033] By setting the height limiting screw 6224 and the knob 6225 in this embodiment, the entire guide mechanism 222 will not fall under the limit of the knob 6225, so that the height can still be maintained when the moving seat 3220 is separated from the surface of the stone 130, and the moving seat 3220 can be made to fit tightly against the upper wall of the accommodating opening 2210 through the knob 6225 during transportation to prevent shaking during transportation.

[0034] In this embodiment, a distance mechanism 223 is provided at the support seat 221; the distance mechanism 223 includes a fixed seat 4230, which is connected to an end face of the support seat 221 away from the road surface and close to the side of the guide plate 32221; the fixed seat 4230 is arranged in a direction perpendicular to the ground; a lifting opening 82310 is provided at the fixed seat 4230, which passes through both ends and both sides of the fixed seat 4230; the lifting opening 82310 also passes through one end of the support seat 221 and is connected to the accommodating opening 2210; a lifting seat 4231 that slides along the length direction of the lifting opening 82310 is provided at the lifting opening 82310; a distance plate 82374232 that can extend between the two vertical plates 32220 is connected to one side of the lifting seat 4231; a first positioning bolt 6236 that can be tightly pressed against the lifting seat 4231 is threadedly fitted at one side of the fixed seat 4230.

[0035] By setting the distance mechanism 223 in this embodiment, the distance plate 82374232 which can be raised and lowered and can be positioned by the first positioning bolt 6236 can be fitted on the side wall of the stone 130 that has been positioned and installed. The thickness of the distance plate 82374232 is the size of the gap between the stones 130. After the distance plate 82374232 is fitted on the stone 130 that has been positioned and installed, the stone 130 that subsequently enters the accommodating space 3223 can fit on the other side of the positioning plate. At this time, the distance plate 82374232 is clamped between the two stones 130, and the gap between the two stones 130 has been reserved; therefore, when the distance mechanism 223 cooperates with the guide mechanism 222, after the stone 130 to be installed enters the accommodating interval 3223 and fits with the distance plate 82374232, the facades of all the stones 130 are automatically kept flush, and the size of the gap and the spacing have been automatically reserved, so that the installation of the stone 130 can be completed more quickly, further improving the construction efficiency.

[0036] In this embodiment, the distance plate 82374232 is composed of a plurality of sub-plates 82370 connected end to end; the thickness of the plurality of sub-plates 82370 is arranged to increase from one end to the other end of the distance plate 82374232, and the sub-plate 82370 with the smallest thickness is arranged close to the vertical plate 32220.

[0037] By setting the distance plate 82374232 in this embodiment to be composed of several sub-plates 82370 of different thicknesses, the operator can place sub-plates 82370 of different thicknesses between two stones 130, so that the distance plate 82374232 can adjust the gap spacing between the two stones 130. Generally speaking, hard curbstones such as granite and marble are suitable for smaller gap widths, generally around 3 mm; while soft curbstones such as sandstone and limestone should have gaps of more than 5 mm; so the distance plate 82374232 can adapt to the installation of curbstones of different materials and requirements; the thickness of several sub-plates 82370 can be increased by 1 mm, for example, the thickness of each sub-plate 82370 is: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc., and one side of each sub-plate 82370 is flush.

[0038] In this embodiment, a guide rod 4233 is provided at the end surface of the support seat 221 along the length direction of the fixed seat 4230; a guide ring 6234 is provided on one side of the lifting seat 4231 and extends to the outside of the lifting port 82310; the guide ring 6234 is slidably matched with the guide rod 4233, and a spring 6235 sleeved on the guide rod 4233 is tightly pressed between the support seat 221 and the guide ring 6234.

[0039] By setting the guide ring 6234, the guide rod 4233 and the spring 6235 in this embodiment, when the distance plate 82374232 is not clamped between the two stones 130, the spring 6235 can support the guide ring 6234 so that the distance plate 82374232 always remains in a raised state, and when the distance plate 82374232 is used to extend into the accommodating interval 3223, the guide ring 6234 will compress the spring 6235, so that the distance plate 82374232 always maintains a force to lift it away from the accommodating interval 3223; therefore, there are two options for operating the distance plate 82374232, one is to continuously press down the distance plate 82374232 with the hand, and it will automatically rise after being released; the other is to position and release its height through the first positioning bolt 6236.

[0040] In this embodiment, one end of the vertical plate 32220 away from the road surface is kept flush with the end of the movable seat 3220 close to the road surface; a calibration mechanism 224 is provided at the vertical plate 32220; the calibration mechanism 224 includes a limit block 5240; the limit block 5240 is fixed to one side of the vertical plate 32220 close to the inner wall surface of the support seat 221; the limit plate 3222 is hinged with a calibration plate 5241 that is kept perpendicular to the vertical plate 32220; the calibration plate 5241 can be flipped 180°, and both sides can be kept flush with one end surface of the vertical plate 32220 close to the movable seat 3220; the distance adjustment plate can be moved between the two calibration plates 5241.

[0041] By setting the calibration plate 5241 in this embodiment, after the two stones 130 are guided and spaced to be flush with each other and the gap is reserved, the height of the two stones 130 can be conveniently calibrated by the calibration plate 5241. Since one side of the calibration plate 5241 is flush with the end faces of the movable seat 3220 and the vertical plate 32220, the top surface of the stone 130 that has been positioned and installed in the former will be in contact with and flush with the end face of the movable seat 3220, and one side of the calibration plate 5241 will be in contact with the end face of the movable seat 3220. The top surface of the stone 130 where the former is positioned and installed is located at the same time, and it is also located above the stone 130 where the latter is positioned and installed. Therefore, by observing the state of the calibration plate 5241, it can be known whether the height of the stone 130 installed in the latter is flush with the height of the stone 130 already positioned and installed in the former. If the latter is higher, the calibration plate 5241 will not fit into the end surface of the vertical plate 32220 but will be tilted. If the latter is lower, there will be a gap between the calibration plate 5241 and the latter stone 130, thereby achieving auxiliary calibration of the height.

[0042] In this embodiment, a connecting mechanism 240 cooperating with the vehicle body 100 is provided at the support seat 221; the connecting mechanism 240 includes a connecting plate 941 and a sliding seat 949; a guide rail is provided at one side of the vehicle body 100 and is arranged along the length direction of the vehicle body 100 and is used for the sliding seat 949 to slide and cooperate; a second hinge seat 943 is provided at one side of the sliding seat 949; a first hinge seat 942 is provided at one side of the support seat 221; the first hinge seat 942 and the second hinge seat 943 are jointly hinged with a connecting plate 941.
