Description

Technical Field

[0001] The present invention relates to the technical field of strand tensioning and anchoring, and particularly relates to a combined extrusion and tensioning machine. Background Art

[0002] A photovoltaic support is a structure used to support solar photovoltaic panels so as to install them on the ground, roof, or other places. During the use of photovoltaic panels, they are affected by various weather conditions such as wind, rain, and snow. Therefore, steel strands are required to fix the connection between the photovoltaic panels and the support to ensure that the photovoltaic panels are firmly installed on the support and prevent displacement or tilt of the photovoltaic panels due to external factors.

[0003] The support forms a stable stress structure by applying prestress to the prestressed steel strand and anchoring it at both ends of the support through an anchor. Currently, wedge anchors are often used for the anchoring of steel strands, but wedge anchors are easily corroded by salt spray. After long-term use, once the anchor teeth of the wedge anchor are rusted, the anchoring force will disappear, resulting in the slippage of the steel strand.

[0004] To solve this problem, an extrusion anchor can be used for anchoring. By deforming the anchor body through extrusion, the anchor body can effectively hold the steel strand. However, when installing steel strands for photovoltaic supports at present, not only the extrusion anchor needs to be installed, but also the steel strand needs to be tensioned. Currently, the existing equipment cannot achieve these two operations simultaneously, which requires carrying multiple pieces of equipment during installation and is inconvenient to use. Summary of the Invention

[0005] The present invention provides a combined extrusion and tensioning machine, which can not only tension the steel strand but also install an extrusion anchor, is convenient to use, and can solve the problems existing in the above-mentioned prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:[[]]

[0008] The linear reciprocating drive mechanism includes a fixed member and a movable member, and the movable member can move along the fixed member.

[0009] One end of the fixed member is provided with an extrusion head, and one end of the movable member close to the extrusion head is provided with an extrusion die. The extrusion head and the extrusion die can cooperate to deform the extrusion anchor body.

[0010] The two one-way locking devices are respectively a one-way locking device one and a one-way locking device two. The directions of restricting the movement of the steel strand by the one-way locking device one and the one-way locking device two are the same. The one-way locking device one is arranged on the movable member, and the one-way locking device two is arranged on the fixed member.

[0011] The extrusion plug and the extrusion die are located between two one-way locking devices, and the steel strand can pass through the extrusion die, the extrusion anchor body, the extrusion plug and the two one-way locking devices.

[0012] Preferably, the first one-way locking device includes a locking cylinder, a limiting cylinder, a pushing block and a plurality of clamping pieces.

A first sliding seal is slidably installed in the stepped inner hole. A second spring is arranged between the first sliding seal and the locking cylinder. A first oil injection hole is formed in the separating cylinder body. Injecting hydraulic oil into the first oil injection hole can drive the first sliding seal to compress the second spring and push the clamping pieces to compress the first spring, so that the clamping pieces loosen the steel strand.

[0014] Preferably, a first fixing seat is fixed at one end of the fixing part close to the extrusion die. The extrusion plug is fixed at one end of the first fixing seat close to the extrusion die. The first fixing seat is fixedly connected to a second fixing seat through a first connecting rod. The second one-way locking device is detachably fixed on the second fixing seat.

The axis line of the outer rod sleeve is parallel to the moving direction line of the movable part along the fixing part.

[0017] Preferably, the second one-way locking device is a clamping plate anchor.

[0018] Preferably, the movable part is an outer cylinder body, the fixing part is an inner cylinder body slidably installed in the outer cylinder body, a fixing cylinder is slidably installed in the inner cylinder body, one end of the fixing cylinder and the outer cylinder body is connected through an end cover, a second sliding seal is fixed on the inner cylinder body, and the second sliding seal can seal the cavity between the outer cylinder body, the fixing cylinder and the end cover.

[0019] Preferably, a second oil injection hole and a third oil injection hole are formed in the outer cylinder body. Injecting oil into the third oil injection hole can drive the inner cylinder body to retract into the outer cylinder body, and injecting oil into the second oil injection hole can drive the inner cylinder body to extend out of the outer cylinder body.

[0020] Preferably, the axial center lines of the fixing member, the movable member, the extrusion die, the extrusion punch, the first one-way locking device and the second one-way locking device coincide, and the steel strand can sequentially pass through the second one-way locking device, the extrusion die, the extrusion punch, the fixing member, the movable member and the first one-way locking device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] By providing the linear reciprocating drive mechanism, the extrusion punch, the extrusion die, the first one-way locking device and the second one-way locking device, the fixing member and the movable member in the linear reciprocating drive mechanism can drive the relative movement between the first one-way locking device and the second one-way locking device to tension the steel strand towards one end. At the same time, by changing the moving stroke of the movable member, the relative movement between the extrusion punch and the extrusion die can also be made to deform the extrusion anchor body, completing the anchoring of the steel strand. By realizing the integration of tensioning and extrusion, the present invention enables the tensioning of the steel strand used in the flexible photovoltaic support and the forming of the extrusion anchor to be completed in one operation, improving the operation efficiency.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 6 shown, an extrusion and tensioning integrated machine provided by an embodiment of the present invention includes a linear reciprocating drive mechanism, a first one-way locking device, a second one-way locking device 23, an extrusion head 211, and an extrusion die 33. The linear reciprocating drive mechanism can be used to drive the extrusion head 211 and the extrusion die 33 to cooperate to deform the extrusion anchor body 9, and can also realize the tensioning of the steel strand by means of the first one-way locking device and the second one-way locking device 23.

[0032] In principle, the linear reciprocating drive mechanism of the present invention can adopt various forms, such as linear drive structures such as oil cylinders, air cylinders, and electric push rods. The stationary part in these structures is called the fixed part, and the movable part is called the movable part. Since it is necessary to cause the extrusion anchor body 9 to deform, it is most appropriate to use an oil cylinder as the drive. In order to make the overall structure more stable when applying pressure to the extrusion anchor, a hollow oil cylinder is used as the drive, which is convenient to align the axis of the steel strand, the extrusion anchor body 9, the extrusion head 211, and the extrusion die 33 with the axis of the hollow oil cylinder.

[0033] Specifically, as Figure 2As shown in the figure, the linear reciprocating drive mechanism (i.e., the hollow oil cylinder) of the present invention includes a fixed member and a movable member. Among them, the movable member is the outer cylinder body 1, and the fixed member is the inner cylinder body 11 slidably installed inside the outer cylinder body 1. During specific use, the inner cylinder body 11 is fixed in position, and the outer cylinder body 1 makes a linear reciprocating motion along the inner cylinder body 11. A fixed cylinder 12 is slidably installed inside the inner cylinder body 11, and one end of the fixed cylinder 12 and the outer cylinder body 1 close to the one-way locking device one are fixedly connected through an end cover 17.

[0034] A second sliding seal 15 is fixed at one end of the inner cylinder body 11 close to the end cover 17. The second sliding seal 15 can seal the cavity between the outer cylinder body 1, the fixed cylinder 12 and the end cover 17. At the same time, a second oil injection hole 13 communicating with this cavity is opened on the outer cylinder body 1. When hydraulic oil is injected from the second oil injection hole 13, the hydraulic oil can push the inner cylinder body 11 to move relative to the outer cylinder body 1, driving the inner cylinder body 11 to extend out of the outer cylinder body 1; a third sliding seal 16 is fixed inside the outer cylinder body 1. The third sliding seal 16 is arranged between the outer cylinder body 1 and the inner cylinder body 11. The third sliding seal 16 can seal the cavity between the outer cylinder body 1, the inner cylinder body 11 and the second sliding seal 15. A third oil injection hole 14 communicating with this cavity is opened on the outer cylinder body 1. Injecting oil into the third oil injection hole 14 can drive the inner cylinder body 11 to retract into the outer cylinder body 1.

[0035] Using hydraulic oil to drive the inner cylinder body 11 and the outer cylinder body 1 to perform linear reciprocating movement can provide sufficient driving force to tension the steel strand and extrude the extrusion anchor body 9.

[0036] A first fixed seat 21 is fixed at one end of the inner cylinder body 11 away from the end cover 17. An extrusion head 211 is fixed at one end of the first fixed seat 21 away from the inner cylinder body 11. Three connecting rods one 22 are fixed on the circumference of the first fixed seat 21. The three connecting rods one 22 are fixedly connected to a second fixed seat 2. A second one-way locking device 23 is installed on the side of the second fixed seat 2 away from the first fixed seat 21. The first one-way locking device is installed at one end of the outer cylinder body 1 away from the extrusion head 211. An active seat one 31 is fixed at one end of the outer cylinder body 1 close to the extrusion head 211. Three connecting rods two 32 are fixed on the circumference of the active seat one 31. The three connecting rods two 32 are fixedly connected to an active seat two 3. An extrusion die 33 is fixed on the side of the active seat two 3 close to the extrusion head 211. The active seat two 3 and the extrusion die 33 are located between the second fixed seat 2 and the extrusion head 211.

[0037] For Figure 2When observed with reference to [a certain reference], both the one-way locking device one and the one-way locking device two 23 restrict the leftward movement of the steel strand, but do not restrict the rightward movement of the steel strand. The one-way locking device two 23 is a wedge anchor structure. A wedge anchor is a fixing device used in construction and civil engineering, and is commonly used for the anchoring and protection of steel strands (also known as steel cables). When installing a steel strand, a wedge anchor is usually used to fix the end of the steel strand to prevent it from detaching or sliding when subjected to tension or other forces. The wedge anchor fixes the steel strand to the structure at one end by means of pressure or clamping, enabling it to be firmly anchored in the engineering project, thereby effectively supporting and enhancing the stability of the structure. The wedge anchor can be fixed on the fixing seat two 2 and can be fixed in a clamping form.

[0038] The one-way locking device one can unlock after unidirectionally locking the steel strand, releasing the one-way limit on the steel strand. The one-way locking device one specifically includes a separating cylinder body 5, a locking cylinder 6, a limiting cylinder 7, a pushing block 71, and three wedge blocks 62. The separating cylinder body 5 is fixedly connected to the outer cylinder body 1 or the end cover 17. A stepped inner hole 51 is provided in the separating cylinder body 5, and a first sliding seal 52 is slidably installed in the stepped inner hole 51. The locking cylinder 6 is fixed on the side of the separating cylinder body 5 away from the outer cylinder body 1. A tapered hole 61 is provided in the locking cylinder 6. The limiting cylinder 7 is fixed at the end of the locking cylinder 6 away from the separating cylinder body 5. The three wedge blocks 62 are circumferentially distributed inside the limiting cylinder 7 and can be inserted into the tapered hole 61. A pushing block 71 and a first spring 72 are provided inside the limiting cylinder 7. The pushing block 71 abuts against the larger ends of the three wedge blocks 62. The first spring 72 can push the pushing block 71 and cause the pushing block 71 to push the three wedge blocks 62 into the tapered hole 61. The wedge blocks 62 cooperate with the tapered hole 61 to reduce the distance between the wedge blocks 62, enabling the wedge blocks 62 to clamp onto the steel strand.

[0039] As Figure 3 shown, a first oil injection hole 54 is provided in the separating cylinder body 5. The first oil injection hole 54 communicates with the stepped inner hole 51. When hydraulic oil is injected into the first oil injection hole 54, it can push the first sliding seal 52 to move to the right. A second spring 53 is provided between the first sliding seal 52 and the locking cylinder 6. When no oil is injected, the second spring 53 can push the first sliding seal 52 to the left, so that the first sliding seal 52 does not contact the wedge blocks 62. In this way, the wedge blocks 62 can clamp the steel strand under the action of the first spring 72. When hydraulic oil is injected into the first oil injection hole 54, the hydraulic oil can drive the first sliding seal 52 to compress the second spring 53 and push the wedge blocks 62 to compress the first spring 72 to the right, causing the wedge blocks 62 to release the steel strand.

[0040] In order to prevent the outer cylinder body 1 and the inner cylinder body 11 from rotating relative to each other, a guiding mechanism is provided. Specifically, the guiding mechanism includes a first guiding connecting plate 4 fixed on the second fixed seat 2 and a second guiding connecting plate 41 fixed on the first movable seat 31. An outer rod sleeve 42 parallel to the axis line of the inner cylinder body 11 is fixed on the first guiding connecting plate 4, and an inner rod 43 movably inserted into the outer rod sleeve 42 is fixed on the second guiding connecting plate 41. By sliding the inner rod 43 along the outer rod, relative rotation of the outer cylinder body 1 and the inner cylinder body 11 is restricted without affecting the relative movement of the inner cylinder body 11 and the outer cylinder body 1.

[0041] The axis lines of the inner cylinder body 11, the outer cylinder body 1, the fixed cylinder 12, the extrusion die 33, the extrusion head 211, the second one-way locking device 23, the separating cylinder body 5, the first sliding seal 52, the locking cylinder 6 and the limiting cylinder 7 of the present invention are all on the same straight line, and the steel strand can sequentially pass through the second one-way locking device 23, the extrusion die 33, the extrusion head 211, the inner cylinder body 11, the fixed cylinder 12, the outer cylinder body 1, the separating cylinder body 5, the first sliding seal 52, the conical hole 61 and the limiting cylinder 7.

[0042] During use: First, fix the second one-way locking device 23 (i.e., the wedge anchor) on the second fixed seat 2, then insert a spacer sleeve 8 between the second fixed seat 2 and the extrusion die 33, and place the extrusion anchor body 9 between the spacer sleeve 8 and the extrusion head 211. Pass the steel strand sequentially through the wedge 62 anchor, the spacer sleeve 8, the extrusion anchor body 9, the extrusion head 211, the first fixed seat 21, the fixed cylinder 12, the first sliding seal 52, the wedge 62, the push block 71 and the limiting cylinder 7. When performing tensioning, control the relative movement of the inner cylinder body 11 and the outer cylinder body 1 by alternately injecting hydraulic oil into the second oil injection hole 13 and the third oil injection hole 14. Figure 2 When observed with [a certain reference], when the outer cylinder body 1 moves to the right, the wedge 62 locks the steel strand in cooperation with the conical hole 61 and pulls the steel strand to the right; when the outer cylinder body 1 moves to the left, the frictional force between the wedge 62 and the steel strand causes the wedge 62 to compress the spring to the right, and the wedge 62 releases the steel strand without restricting the movement of the steel strand. After the outer cylinder body 1 moves back and forth several times, the steel strand is tightened. When it is necessary to extrude the extrusion anchor body 9, first inject hydraulic oil into the first oil injection hole 54 to make the first sliding seal 52 push the wedge 62 to release the restriction on the steel strand, and then make the outer cylinder body 1 move a greater distance to the right. Under the action of the extrusion head 211 and the extrusion die 33, the extrusion anchor body 9 is extruded and deformed so that the diameter of the extrusion anchor body 9 is basically the same as the diameter of the spacer sleeve 8. At this time, the extrusion anchor body 9 firmly clamps the steel strand, completing the tensioning and anchoring of the steel strand. Then separate the wedge anchor from the second fixed seat 2, and draw out the steel strand, the spacer sleeve 8 and the deformed extrusion anchor body 9 from the present invention.
