[0002] The static load test platform is used for static load tests on pile foundations. It generally includes a horizontally set table and a beam. The table is set horizontally, and the beam is located below the table. A concrete block or steel block of a certain weight is placed on the table. A jack is set on the pile foundation directly below the beam. The jack is used to push the beam, and the reaction force acts on the pile foundation to conduct a static load test. Since there are generally many locations that need to be tested at the test site, when the test at a certain location is completed, the test platform needs to be moved to the next location for testing.

They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0031] Please also read Figure 1 Now, the static load test platform provided by the present invention is described. The static load test platform includes a horizontally arranged table plate 1 and a crossbeam 2 located below the table plate 1, and also includes two support units, which are symmetrically arranged on both sides of the crossbeam 2. The support units include a support frame 31 and a walking track 32. The support frame 31 is connected to the table plate 1. The walking track 32 is connected to the support frame 31. Among them, the crossbeam 2 is connected to the table plate 1.

[0032] 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 frame 31 to move, thereby changing the position of the test platform, thereby avoiding the inconvenience of using lifting equipment to change the position of the static load test platform.

[0033] In some embodiments, see Figure 1 , Figure 2 and Figure 4 , the support bracket 31 supports the table plate 1, and the support 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 support bracket 31, and the positioning shafts 33 are slidably penetrated into the table plate 1. The support bracket 31 is connected to the table plate 1 by the sliding cooperation between the positioning shaft 33 and the table plate 1. Due to the large size of this experimental platform, it is inconvenient to transport the whole after the experiment is completed. At this time, the table plate 1 can be slid upward to disengage from the positioning shaft 33, so that the experimental platform can be disassembled for transportation. In this embodiment, the two walking tracks 32 can be driven by dual motors or dual hydraulic motors in the prior art.

[0034] In some embodiments, see Figure 1 and Figure 8 The table 1 has a connecting portion 11 at both ends along the length direction 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 and the table 1 slide together. 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 member 4 includes a limiting portion 41 and a fixing portion 42. The fixing portion 42 is fixedly connected to the beam 2. The limiting portion 41 is slidably arranged on the connecting portion 11 at the location. The two fixing portions 42 are respectively located at the relative outer sides of the two connecting portions 11 and slide together with the two connecting portions 11. 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, so that the beam 2 and the table 1 are slidably connected together. When the table 1 slides upward and disengages from the positioning shaft 33, the beam 2 can slide away from the table 1, thereby disconnecting the connection between the table 1 and the beam 2, and then making the transportation of the experimental platform more convenient. When the experimental platform is moved to the vicinity of the pile foundation, if the cross beam 2 is not aligned with the pile foundation, the cross beam 2 can be oriented to the pile foundation by sliding.

[0035] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The static load test platform also includes two connecting units, which are respectively located on both sides of the support frame 31 along the length direction of the crossbeam 2, and the connecting units include two fixing members 51, a connecting shaft 52 and two sliding shafts 53. The two fixing members 51 are respectively fixedly connected to the two support frames 31. The connecting shaft 52 is horizontally arranged and placed on the two fixing members 51. The two sliding shafts 53 are both fixedly connected to the connecting shaft 52, and the sliding shaft 53 is vertically arranged. The two sliding shafts 53 are respectively slidably inserted into the two fixing members 51. When the experimental platform is assembled, the two sliding shafts 53 in the connecting unit are respectively slid into the two fixing members 51 and the fixing members 51 support the connecting shaft 52, so that the two supporting units can be locked together, so as to facilitate the table plate 1 to be sleeved on the positioning shafts 33 of the two supporting units.

[0036] In some embodiments, the feature support unit may be used 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 push-out assembly, which is located between the support bracket 31 and the cross beam 2. The push-out assembly includes a base 341, a rotating shaft 342, two support arms 343, a connecting pipe 344 and a push-out shaft 345. The base 341 is fixedly connected to the support bracket 31. The rotating shaft 342 is parallel to the cross beam 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 fitted with the base 341 and are 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 arranged in the connecting pipe 344. The push-out shaft 345 is arranged in the connecting pipe 344 and is provided with an external thread threadedly connected to the internal thread. Among them, the rotation of the rotating shaft 342 enables the ejection shaft 345 to have an ejection position horizontally facing the beam 2. The support arm 343 realizes a rotational connection with the base 341 through the rotating shaft 342, thereby being able to drive the connecting tube 344 and the ejection shaft 345 to rotate. When the beam 2 needs to slide, the ejection assembly that the beam 2 is to be away from is selected, and the support arm 343 in the ejection assembly is driven to rotate until the ejection shaft 345 in the ejection assembly reaches the ejection position, at which time the ejection shaft 345 is driven to rotate, so that the ejection shaft 345 approaches the beam 2 and pushes the beam 2 to slide. When this experimental platform needs to be transported, the ejection 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.

[0037] In some embodiments, the above-mentioned characteristic ejection shaft 345 can be used as follows Figure 4 and Figure 5 See 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.

[0038] In some embodiments, the above-mentioned feature 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 limiter 346 and a locking shaft 347. The limiter 346 is fixedly connected to one of the support arms 343. The locking shaft 347 is horizontally arranged, and the locking shaft 347 is slidably inserted into the limiter 346. When the ejection shaft 345 is in the ejection position, the locking shaft 347 can slide into the support bracket 31. In this way, the rotation of the support arm 343 can be limited, so that the ejection shaft 345 is kept in the ejection position, and the operator only needs to drive the ejection shaft 345 to rotate.

[0039] In some embodiments, the feature support unit may be used as follows: Figure 1 See the structure shown. Figure 1 The support unit further includes a connecting member 35 and a ground-inserting nail 36. The connecting member 35 is fixedly connected to the support bracket 31. The ground-inserting nail 36 is vertically arranged and slidably penetrates the connecting member 35, and the tip of the ground-inserting nail 36 is used to be inserted into the ground. When the table 1 is sleeved on the positioning shaft 33, in order to prevent the two support units from being displaced, the two ground-inserting nails 36 can be inserted into the ground first, thereby limiting the movement of the two support units.

[0040] In some embodiments, see Figure 1 and Figure 4 The ground nail 36 and the push-up assembly are located on the same side of the support bracket 31. When the rotation of the rotating shaft 342 makes the push-up shaft 345 in a vertical state, the downward movement of the push-up shaft 345 enables the push-up shaft 345 to push the ground nail 36 downward. The push-up shaft 345 pushes the ground nail 36 to be inserted into the ground. In this embodiment, when the push-up shaft 345 is in a vertical state, one end of the push-up shaft 345 for pushing faces the ground.

[0041] In some embodiments, see Figure 4The locking shaft 347 matches the driving groove 3451, so that one end of the locking shaft 347 can slide into one of the driving grooves 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 in 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 realizing the ejection of the cross beam 2.

[0042] In some embodiments, the above-mentioned characteristic platform 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 top 1 is provided with an avoidance groove 12, thereby reducing the contact area between the beam 2 and the table top 1, that is, reducing the resistance of the beam 2 when sliding.

[0043] In some embodiments, see Figure 8 and Fig. 9 The static load test platform also includes an insert 6, which can be slidably inserted into the avoidance groove 12. When the experimental platform is not conducting an experiment, the table 1 can be disassembled, and then the crossbeam 2 can be slid away from the table 1, and then the table 1 can be turned over and slidably sleeved on 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 be temporarily used as a material transport vehicle.

[0044] 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 protection scope of the present invention.
