Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a geogrid welding device. Background Art

[0002] Geogrid is a main geosynthetics material, often used as reinforcement for reinforced soil structures or reinforcement for composite materials. It generally consists of a number of ribs arranged vertically and horizontally, and the geogrid is formed by welding and fixing at the junction of the ribs.

[0003] The application document with application number CN202321813847.2 discloses a geogrid welding machine. In order to adapt to the welding requirements of geogrids of different specifications, the welding head is slidably set and is equipped with a fixing plate to complete the fixing of the welding head. However, when adjusting, it is necessary to manually adjust them one by one. Although it is equipped with a pointer and scale lines, during adjustment, the position of each welding head needs to be calculated to complete the adjustment work, which makes the position adjustment of the welding head too complicated. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a geogrid welding device.

[0005] The technical solution of this utility model is as follows:

[0006] A geogrid welding device comprises a supporting mechanism, on which a welding mechanism is provided. The supporting mechanism can provide support for the welding mechanism, and the welding forming work of the geogrid can be completed by the welding mechanism.

[0007] As the core technical concept of the present utility model, an adjustment mechanism is also provided on the upper side of the welding mechanism for vertical sliding, and a driving machine capable of driving the adjustment mechanism to rise and fall is also provided on the welding mechanism. Specifically, the welding mechanism comprises a welding frame and a plurality of welding units arranged transversely and linearly thereon and slidingly arranged along the arrangement direction, and the welding units can complete the welding and fixing work at the intersection of the longitudinal and transverse ribs of the geogrid, and a top spring is provided between the welding units at both ends and the welding frame, and the adjustment mechanism comprises a lifting frame and a plurality of plug-ins arranged transversely and linearly thereunder, one of which is fixedly arranged, and the other slide blocks are slidingly arranged along the arrangement direction, and the plug-ins are arranged alternately with the welding units, and the lower part thereof is arranged on both sides along the arrangement direction thereof. It is an inclined structure, and the upper end of the welding unit is in sliding contact with the inclined surface of the plug block near it. When the adjusting mechanism is driven to rise by the driving machine, the width of the plug block supported between two adjacent welding units is reduced. In conjunction with the sliding setting of the plug block, a number of welding units can be contracted synchronously under the action of the top spring, that is, the spacing between a number of welding units can be reduced synchronously, and conversely, the spacing between a number of welding units can be expanded synchronously. On the one hand, the adjustment work of the welding position of the welding unit can be completed more easily through the driving machine, and on the other hand, it only needs to control the lifting and lowering of the adjustment mechanism and the lifting distance, which can not only realize the synchronous adjustment of the spacing between a number of welding units, but also make the adjustment work of the welding position of the welding unit more convenient and quick.

[0008] As a geogrid welding device as described above, as a preferred embodiment, the welding units are provided with an even number, and the middle plug block is fixedly arranged. At this time, the lateral displacement of several welding units can be quickly determined according to the position of the middle plug block. At the same time, several welding units can be simultaneously expanded toward both ends, or converged in the middle from the two ends, so that the position adjustment work of the welding units can be carried out smoothly.

[0009] In the geogrid welding device as described above, in order to ensure the vertical sliding stability of the lifting frame and prevent it from tipping over during lifting, sliding rods are vertically provided on both sides of the welding frame, and the lifting frame slidably cooperates with the sliding rods through sliding cylinders on both sides.

[0010] In order to further ensure the stability of the vertical sliding of the lifting frame so that both ends along the arrangement direction of the plug blocks can be lifted and lowered synchronously, multiple sliding rods are provided on both sides of the welding frame along the arrangement direction of the welding units.

[0011] A geogrid welding device as described above, in order to ensure the stability of the lateral sliding of the welding unit and to ensure that the synchronous adjustment of the spacing can be successfully completed through the lifting and lowering of the adjustment mechanism, the welding frame includes two parallel cross bars, and a number of the welding units are slidably arranged between the two cross bars.

[0012] As a preferred embodiment, the welding unit includes a slider, the upper end of which is detachably provided with a contact piece that contacts the inclined surface of the plug block, so that after the welding device (the above-mentioned geogrid welding device) has been used for a long time, the synchronous adjustment of the spacing between several welding units can still be ensured by replacing the worn contact piece.

[0013] In order to enable the welding unit to slide laterally more smoothly under the action of the insert block, the contact piece is a roller.

[0014] As a further preferred embodiment, in order to avoid the influence of wear on the synchronous adjustment of the spacing, the roller and the insert are both made of steel.

[0015] In the geogrid welding device as described above, in order to make it easier to control the lifting distance of the adjustment mechanism and thus make it easier to control the spacing between the welding units, the driving machine adopts a linear motor.

[0016] As for the setting method of the plug block, a slide groove is provided on the lower side of the lifting frame, and the upper end of the plug block slides with the slide groove. In order to make the matching installation of the plug block and the lifting frame more convenient and facilitate the maintenance and replacement of the plug block, the two ends of the slide groove pass through the two ends of the lifting frame along the direction of the plug block arrangement.

[0017] The beneficial effect of the utility model is that the utility model is a geogrid welding device. When the driving machine drives the adjustment mechanism to rise, the width of the plug block supported between two adjacent welding units is reduced, and the plug block is set to slide. At this time, a number of welding units can be synchronously contracted under the action of the top spring, that is, the spacing between the several welding units can be synchronously reduced. Conversely (when the driving machine drives the adjustment mechanism to descend), the spacing between the several welding units can be synchronously expanded. On the one hand, the adjustment work of the welding position of the welding unit can be completed more easily through the driving machine. On the other hand, it only needs to control the lifting and lowering of the adjustment mechanism and the lifting distance, which can not only realize the synchronous adjustment of the spacing between the several welding units, but also make the adjustment work of the welding position of the welding unit more convenient and quick.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] This embodiment provides a geogrid welding device, see Figure 1 and Figure 2 , including a supporting mechanism (not shown), which can be a supporting frame, on which a welding mechanism 1 is provided, and the supporting frame can provide a stable supporting effect for the welding mechanism 1, and the welding mechanism 1 can complete the welding and forming work of the geogrid. The structure of the welding device (the above-mentioned geogrid welding device) is described in detail below.

[0030] In this embodiment, as the core technical concept of the utility model, an adjustment mechanism 2 is also vertically slidably provided on the upper side of the welding mechanism 1, and a driving machine capable of driving the adjustment mechanism 2 to rise and fall is also provided on the welding mechanism 1. The welding mechanism 1 comprises a welding frame 11 and a plurality of welding units 12 arranged laterally linearly thereon and slidingly arranged along the arrangement direction. The welding unit 12 can complete the welding and fixing work at the intersection of the longitudinal and transverse ribs of the geogrid, and the lifting and lowering of the welding mechanism 1 can complete the position of the welding unit 12, that is, the synchronous adjustment of the spacing between the plurality of welding units 12.

[0031] As for the structure of the welding mechanism 1, Figure 3The welding frame 11 is laterally arranged on the upper side of the support frame, and includes two parallel horizontal bars, and connecting rods are connected at both ends of the two horizontal bars, so that the welding frame 11 is a rectangular frame structure as a whole. Several welding units 12 are slidably arranged inside the welding frame 11, that is, between the two horizontal bars, so as to ensure the stability of the lateral sliding of the welding unit 12, and further ensure that the synchronous adjustment of the spacing between several welding units 12 can be successfully completed through the lifting and lowering of the adjustment mechanism 2.

[0032] Combination Figure 4 The welding unit 12 includes a slider 121 vertically arranged inside the welding frame 11, and slide grooves are arranged on both sides of the slider 121 and slidingly cooperate with the two slide rods 13 through the slide grooves on both sides. A welding machine 122 is arranged on the lower side of the slider 121, and the welding and fixing work at the intersection of the longitudinal and transverse ribs of the geogrid can be completed by the welding machine 122.

[0033] As for the structure of the adjustment mechanism 2, Figure 5 It includes a lifting frame 21 which is liftable and arranged above the welding frame 11. A plurality of plug blocks 23 are arranged linearly in a transverse direction along the arrangement direction of the welding units 12 on the lower side of the lifting frame 21. One of the plug blocks 23 is fixedly arranged, and the remaining sliders 121 are slidably arranged along the arrangement direction. The plug blocks 23 are arranged alternately with the welding units 12, that is, a plurality of the plug blocks 23 are arranged one by one above between two adjacent welding units 12. The lower part of the plug block 23 is an inclined structure on both sides along the arrangement direction thereof, that is, the width of the middle part of the plug block 23 (along the arrangement direction thereof) is greater than the width of the lower end thereof, and the upper end of the welding unit 12 is in sliding contact with the inclined surface of the plug block 23 close thereto.

[0034] On the basis of the above structure, in terms of the cooperation mode between the adjustment mechanism 2 and the welding mechanism 1, a top spring (not shown) is provided between the welding units 12 at both ends and the welding frame 11, and the top spring is arranged between the slider 121 of the welding units 12 at both ends and the connecting rods at both ends, so that the direction of the top spring tightening force on the welding units 12 at both ends points to the welding unit 12 in the middle. When the adjustment mechanism 2 is driven to rise by the driving machine, the width of the plug block 23 supported between the two adjacent welding units 12 is reduced, and the plug block 23 is slidably arranged. At this time, several welding units 12 can be synchronously contracted under the action of the top spring, that is, the spacing between several welding units 12 can be synchronously reduced, and vice versa. The spacing between several welding units 12 can be synchronously expanded, on the one hand, the adjustment work of the welding position of the welding unit 12 can be completed more easily through the driving machine, and on the other hand, it only needs to control the lifting and lowering of the adjustment mechanism 2 and the lifting distance, so that the synchronous adjustment of the spacing between several welding units 12 can be achieved, so that the adjustment work of the welding position of the welding unit 12 can be completed more conveniently and quickly.

[0035] Furthermore, a slide groove is provided on the lower side of the lifting frame 21, and the upper end of the plug block 23 slides in cooperation with the slide groove. In order to facilitate the cooperation and installation of the plug block 23 and the lifting frame 21 and facilitate the maintenance and replacement of the plug block 23, the two ends of the slide groove pass through the two ends of the lifting frame 21 along the arrangement direction of the plug block 23.

[0036] In this embodiment, as a preferred implementation, the welding units 12 are provided with an even number, and the middle plug block 23 is fixedly arranged. At this time, the lateral displacement of several welding units 12 can be quickly determined according to the position of the middle plug block 23. At the same time, several welding units 12 can be simultaneously expanded toward both ends, or synchronously aggregated from both ends to the middle, so that the position adjustment work of the welding units 12 can be carried out more smoothly.

[0037] As for the cooperation between the welding unit 12 and the plug block 23, the upper end of the slider 121 is detachably provided with a contact piece that contacts the inclined surface of the plug block 23, so that after the welding device has been used for a long time, the synchronous adjustment of the spacing between several welding units 12 can still be guaranteed by replacing the worn contact pieces.

[0038] In order to enable the welding unit 12 to slide laterally more smoothly under the action of the insert block 23 , the contact member is a roller 123 , and the axis of the roller 123 is perpendicular to the arrangement direction of the welding unit 12 .

[0039] As a further preferred embodiment, in order to avoid the influence of wear on the synchronous adjustment of the spacing, the roller 123 and the insert block 23 are both made of steel.

[0040] As for the lifting connection method of the adjustment unit, in order to ensure the stability of the vertical sliding of the lifting frame 21 and prevent it from tipping over during the lifting process, sliding rods 13 are vertically provided on both sides of the welding frame 11, and the lifting frame 21 slides and cooperates with the sliding rods 13 through the slide cylinders 22 on both sides.

[0041] To further ensure the vertical sliding stability of the lifting frame 21 and enable both ends of the lifting frame 21 along the arrangement direction of the insert blocks 23 to be lifted and lowered synchronously, multiple sliding rods 13 are provided on both sides of the welding frame 11 along the arrangement direction of the welding units 12 .

[0042] On the basis of the above structure, a top plate 14 is also provided at the top end of the plurality of sliding rods 13, and the driving motor is fixedly arranged in the middle of the upper side of the top plate 14. In order to make it more convenient to control the lifting distance of the adjustment mechanism 2, and thus make it easier to control the spacing between the plurality of welding units 12, the driving motor adopts a linear motor 3, a driving end of which passes through the top plate 14 and is connected to the lifting frame 21.
