Description

Technical Field

[0001] The present invention belongs to the technical field of experimental platforms, and more specifically, relates to a static load experimental platform. Background Art

[0002] Static load test platforms are used for static load tests on pile foundations. They generally consist of a horizontally mounted platform and a crossbeam. The platform is horizontally mounted, with the crossbeam positioned below it. Concrete or steel blocks of a certain weight are placed on the platform, and a jack is installed on the pile foundation directly below the crossbeam. The jack pushes against the crossbeam, and the reaction force acts on the pile foundation, allowing for static load testing. Because multiple locations typically require testing at a test site, once a test at one location is completed, the platform needs to be moved to the next location for testing. Due to the heavy weight of the platform and crossbeam, lifting equipment is required to reposition the static load test platform, which is inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to provide a static load test platform, aiming to solve the problem that it is inconvenient to change the position of the static load test platform with the help of lifting equipment.

[0004] To achieve the above objectives, the present invention employs a technical solution comprising: providing a static load test platform comprising a horizontally disposed platform and a crossbeam positioned below the platform; and two support units symmetrically disposed on either side of the crossbeam. Each support unit comprises a support bracket and a running track. The support bracket is connected to the platform. The running track is connected to the support bracket. The crossbeam is connected to the platform.

[0005] In a possible implementation, the support bracket supports the table, and the support unit further includes a plurality of positioning shafts, each of which is vertically arranged and fixed on the support bracket and slidably penetrates the table.

[0006] In one possible implementation, the tabletop has connecting parts at both ends along the length direction of the beam. The connecting parts are horizontally arranged in a long strip structure and the length direction is perpendicular to the beam. The beam and the tabletop are slidably fitted together, and the static load test platform also includes two sliding parts. The two sliding parts are respectively provided at the two connecting parts. The sliding parts include a limiting part and a fixing part. The fixing part is fixedly connected to the beam, and the limiting part is slidably provided on the connecting part at the location. The two fixing parts are respectively located on the opposite outsides of the two connecting parts and are slidably fitted with the two connecting parts.

[0007] In one possible implementation, the static load test platform further includes two connecting units, each located on either side of the support frame along the length direction of the crossbeam, and each connecting unit includes two fixing members, a connecting shaft, and two sliding shafts. The two fixing members are respectively fixedly connected to the two support frames. The connecting shaft is horizontally arranged and placed on the two fixing members. The two sliding shafts are both fixedly connected to the connecting shaft, and the sliding shafts are vertically arranged. The two sliding shafts slide through the two fixing members.

[0008] In one possible implementation, the support unit further includes a pushing assembly, which is located between the support bracket and the crossbeam, and the pushing assembly includes a base, a rotating shaft, two support arms, a connecting pipe and a pushing shaft. The base is fixedly connected to the support bracket. The rotating shaft is parallel to the crossbeam and is rotatably arranged inside the base. The two support arms are respectively located on both sides of the base along the axial direction of the rotating shaft, and the two support arms are fitted with the base and are both fixedly connected to the rotating shaft. The connecting pipe is located between the two support arms and is fixedly connected to both support arms, the axis of the connecting pipe is perpendicular to the axis of the rotating shaft, and an internal thread is provided in the connecting pipe. The pushing shaft is arranged inside the connecting pipe and is provided with an external thread threadedly connected to the internal thread. Wherein, the rotation of the rotating shaft enables the pushing shaft to have a pushing position horizontally facing the crossbeam.

[0009] In a possible implementation, a side wall of the ejection shaft is provided with a plurality of driving grooves, and the plurality of driving grooves are evenly distributed around the axis of the ejection shaft.

[0010] In one possible implementation, the ejection assembly further includes a stopper and a locking shaft. The stopper is fixedly connected to one of the support arms. The locking shaft is horizontally disposed and slidably extends through the stopper. When the ejection shaft is in the ejection position, the locking shaft can slide into the support bracket.

[0011] In one possible implementation, the support unit further includes a connecting member and a ground spike. The connecting member is fixedly connected to the support bracket. The ground spike is vertically arranged and slidably inserted into the connecting member, and the tip of the ground spike is used to be inserted into the ground.

[0012] In a possible implementation, the ground nail and the ejection assembly are located on the same side of the support bracket. When the rotation of the rotating shaft causes the ejection shaft to be in a vertical state, the downward movement of the ejection shaft enables the ejection shaft to push the ground nail downward.

[0013] In a possible implementation, the locking shaft matches the driving slots, so that one end of the locking shaft can slide into one of the driving slots.

[0014] In the embodiment of the present application, the walking track supports the platform and the crossbeam through the support frame to move, thereby changing the position of the experimental platform, thereby avoiding the inconvenience of needing to use lifting equipment to change the position of the static load experimental platform.

When an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] The directions or positional relationships indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0023] Please also refer to Figure 1 The static load test platform provided by the present invention is now described. The static load test platform includes a horizontally arranged tabletop 1 and a crossbeam 2 located below the tabletop 1. It also includes two support units, symmetrically arranged on either side of the crossbeam 2. The support units include a support bracket 31 and a walking track 32. The support bracket 31 is connected to the tabletop 1. The walking track 32 is connected to the support bracket 31. The crossbeam 2 is connected to the tabletop 1.

[0024] Compared with the prior art, the static load test platform provided by the present invention has a walking track 32 that supports the platform 1 and the crossbeam 2 through the support bracket 31 to move, thereby changing the position of the test platform, thereby avoiding the inconvenience of needing to use lifting equipment to change the position of the static load test platform.

[0025] In some embodiments, see Figure 1 、 Figure 2 and Figure 4 , the supporting bracket 31 supports the table 1, and the supporting unit also includes a positioning shaft 33. There are multiple positioning shafts 33, and the positioning shafts 33 are vertically arranged and fixed on the supporting bracket 31, and the positioning shafts 33 are slidably passed through the table 1. The supporting bracket 31 is connected to the table 1 by the sliding fit of the positioning shaft 33 and the table 1. Due to the large size of this experimental platform, the overall transportation after the experiment is completed is relatively inconvenient. At this time, the table 1 can be slid upward to disengage from the positioning shaft 33, so that the experimental platform can be disassembled and transported. In this embodiment, the two walking tracks 32 can be driven by dual motors or dual hydraulic motors in the prior art.

[0026] In some embodiments, see Figure 1 and Figure 8 The table 1 has a connecting portion 11 at both ends along the length of the beam 2. The connecting portion 11 is a horizontally arranged long strip structure and its length direction is perpendicular to the beam 2. The beam 2 slides and fits with the table 1. The static load test platform also includes two sliding members 4. The two sliding members 4 are respectively arranged at the two connecting portions 11. The sliding members 4 include a limiting portion 41 and a fixing portion 42. The fixing portion 42 is fixedly connected to the beam 2, and the limiting portion 41 is slidably arranged on the connecting portion 11 at the location. The two fixing portions 42 are respectively located on the opposite outer sides of the two connecting portions 11 and slide and fit with the two connecting portions 11 respectively. The table 1 can limit the upward movement of the beam 2. The two connecting portions 11 respectively support the two limiting portions 41, thereby limiting the upward movement of the beam 2, thereby slidingly connecting the beam 2 and the table 1 together. When the table 1 slides upward and disengages from the positioning shaft 33, the beam 2 can slide and disengage from the table 1, thereby disconnecting the table 1 from the beam 2, and making the transportation of the experimental platform more convenient. When the experimental platform is moved to the vicinity of the pile foundation, if the crossbeam 2 is not aligned with the pile foundation, the crossbeam 2 can be oriented by sliding.

[0027] In some embodiments, see Figure 1 、 Figure 3 and Figure 4The static load test platform also includes two connecting units, which are respectively located on both sides of the support bracket 31 along the length direction of the beam 2. The connecting units include two fixing parts 51, a connecting shaft 52 and two sliding shafts 53. The two fixing parts 51 are respectively fixedly connected to the two support brackets 31. The connecting shaft 52 is arranged horizontally and placed on the two fixing parts 51. The two sliding shafts 53 are both fixedly connected to the connecting shaft 52, and the sliding shaft 53 is arranged vertically. The two sliding shafts 53 are respectively slid into the two fixing parts 51. When the experimental platform is assembled, the two sliding shafts 53 in the connecting unit are respectively slid into the two fixing parts 51 and the fixing parts 51 support the connecting shaft 52, so that the two support units can be locked together, thereby facilitating the table plate 1 to be sleeved on the positioning shafts 33 of the two support units.

[0028] In some embodiments, the feature support unit may be configured as follows: Figure 1 、 Figure 4 and Figure 7 See the structure shown. Figure 1 、 Figure 4 and Figure 7 The support unit also includes a pushing assembly, which is located between the support bracket 31 and the crossbeam 2. The pushing assembly includes a base 341, a rotating shaft 342, two support arms 343, a connecting pipe 344 and a pushing shaft 345. The base 341 is fixedly connected to the support bracket 31. The rotating shaft 342 is parallel to the crossbeam 2 and is rotatably arranged in the base 341. The two support arms 343 are respectively located on both sides of the base 341 along the axial direction of the rotating shaft 342. The two support arms 343 are in contact with the base 341 and are both fixedly connected to the rotating shaft 342. The connecting pipe 344 is located between the two support arms 343 and is fixedly connected to both support arms 343. The axis of the connecting pipe 344 is perpendicular to the axis of the rotating shaft 342, and an internal thread is provided in the connecting pipe 344. The pushing shaft 345 is arranged in the connecting pipe 344 and is provided with an external thread that is threadedly connected to the internal thread. Among them, the rotation of the rotating shaft 342 enables the pushing shaft 345 to have a pushing position horizontally facing the beam 2. The support arm 343 is connected to the base 341 through the rotating shaft 342, so that the connecting tube 344 and the pushing shaft 345 can be driven to rotate. When the beam 2 needs to slide, the pushing assembly that the beam 2 wants to move away from is selected, and the support arm 343 in the pushing assembly is driven to rotate until the pushing shaft 345 in the pushing assembly reaches the pushing position. At this time, the pushing shaft 345 is driven to rotate, so that the pushing shaft 345 approaches the beam 2 and pushes the beam 2 to slide. When this experimental platform needs to be transported, the pushing shaft 345 is made to reach a vertical state by the rotation of the support arm 343, thereby reducing the volume of the support unit.

[0029] In some embodiments, the above-mentioned feature ejection shaft 345 can be used as follows Figure 4 and Figure 5See the structure shown. Figure 4 and Figure 5 The side wall of the ejection shaft 345 is provided with a plurality of driving grooves 3451, and the plurality of driving grooves 3451 are evenly distributed around the axis of the ejection shaft 345. One end of the bar material can be inserted into the driving groove 3451 to drive the ejection shaft 345 to rotate.

[0030] In some embodiments, the above-mentioned ejection assembly can be used as follows Figure 4 and Figure 6 See the structure shown. Figure 4 and Figure 6 The ejection assembly further includes a stopper 346 and a locking shaft 347. The stopper 346 is fixedly connected to one of the support arms 343. The locking shaft 347 is arranged horizontally and slides through the stopper 346. When the ejection shaft 345 is in the ejection position, the locking shaft 347 can slide into the support bracket 31. This restricts the rotation of the support arm 343, thereby keeping the ejection shaft 345 in the ejection position. The operator only needs to drive the ejection shaft 345 to rotate.

[0031] In some embodiments, the feature support unit may be configured as follows: Figure 1 See the structure shown. Figure 1 The support unit also includes a connector 35 and a ground spike 36. The connector 35 is fixedly connected to the support bracket 31. The ground spike 36 is vertically arranged and slides through the connector 35. The tip of the ground spike 36 is designed to be inserted into the ground. When the table 1 is placed on the positioning shaft 33, to prevent the two support units from shifting, the two ground spikes 36 can be driven into the ground to limit their movement.

[0032] In some embodiments, see Figure 1 and Figure 4 The ground nail 36 and the pushing assembly are located on the same side of the support bracket 31. When the rotation of the rotating shaft 342 causes the pushing shaft 345 to be in a vertical position, the pushing shaft 345 moves downward, causing the pushing shaft 345 to push the ground nail 36 downward. The pushing shaft 345 pushes the ground nail 36, thereby inserting the ground nail 36 into the ground. In this embodiment, when the pushing shaft 345 is in a vertical position, the end of the pushing shaft 345 used for pushing is facing the ground.

[0033] In some embodiments, see Figure 4The locking shaft 347 matches the driving slots 3451, so that one end of the locking shaft 347 can slide into one of the driving slots 3451, thereby driving the ejection shaft 345 to rotate. Since there are two locking shafts 347, one of the locking shafts 347 can be inserted into the stopper 346 and the support bracket 31 of one of the support units, and the other locking shaft 347 can be used to drive the ejection shaft 345 in the support unit to rotate, thereby ejecting the crossbeam 2.

[0034] In some embodiments, the above-mentioned characteristic platen 1 can be used as follows Figure 1 and Figure 8 See the structure shown. Figure 1 and Figure 8 The bottom surface of the table 1 is provided with an avoidance groove 12, thereby reducing the contact area between the beam 2 and the table 1, that is, reducing the resistance of the beam 2 when sliding.

[0035] In some embodiments, see Figure 8 and Figure 9 The static load test platform also includes an insert 6 that can be slidably inserted into the avoidance groove 12. When the experimental platform is not conducting experiments, the platform 1 can be disassembled, and the crossbeam 2 can be slid off the platform 1. The platform 1 is then flipped over and slid onto the positioning shaft 33. At this time, the insert 6 can be slid into the avoidance groove 12. In this way, materials can be placed in the insert 6, and the experimental platform can temporarily serve as a material transport vehicle.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
