Description

Technical Field

[0001] The invention relates to the technical field of in-situ testing, and in particular to a portable static penetration device. Background Art

[0002] With the acceleration of urban construction and the strengthening of quality supervision of construction projects, static penetration testing, as a common type of foundation bearing capacity detection in situ testing, has been applied in more and more fields. It can be used to estimate the bearing capacity of soft soil, general clay soil, silt soil, sandy soil, and foundation (soil) containing a small amount of gravel and that has been treated with strong compaction and preloading. Therefore, the research and development of static penetration testing equipment trolleys is of great significance. The development of this trolley can reduce the labor cost of the penetration equipment during transportation, reduce the safety risks during transportation, and make positive contributions to the improvement and development of engineering detection.

[0003] At present, static penetration testing equipment is still at the stage of pure manual transportation. Due to the complexity and diversity of the sites to be inspected, vehicles cannot reach the sites, and there is currently no suitable means of transportation. It can only rely on manual lifting, which takes a long time, is costly, and poses a great safety hazard. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a portable static penetration probe device, which is easy to carry, can save manpower and reduce safety hazards.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A portable static penetration device includes a static penetration machine, a probe rod, and a trolley for carrying the static penetration machine, wherein the trolley includes wheels and a frame; the frame includes vertical rods symmetrically distributed on both sides and connected to the wheels, and a cross bar connected to the same end of the vertical rods, a pull rod is welded to one end of the vertical rod close to the cross bar, and the other end of the vertical rod is provided with an arc-shaped fixed foot extending upward at the tail end, and a card is welded to the fixed foot, and two symmetrically distributed sockets are provided on the bottom crossbeam of the static penetration machine, the size of the sockets is the same as the size of the card, and the spacing between the two sockets is the same as the spacing between the two cards. The sockets and the cards can be fully matched and engaged, so that the bottom of the static penetration machine is fixed on the trolley.

[0007] Furthermore, a support platform is welded to the upper end of the crossbar. When the static penetration tester is placed on the trolley, the support platform supports the top of the device to prevent the chain part at the side end of the static penetration tester from being damaged by lateral pressure.

[0008] Furthermore, a rotatable support rod is provided at the side end of the cross bar. The support rod is connected to the side end of the cross bar by a latch. The support rod may be an L-shaped support rod. During loading and unloading of the static penetration probe, the support rod is turned toward the ground to support the trolley and prevent the trolley from moving.

[0009] Furthermore, the upper end of the crossbar is provided with fixing ribs connected to both sides of the support platform. The fixing ribs are connected to the crossbar by screws or buckles, so that the static penetration machine can be more firmly fixed on the trolley, so that it is not easy to slide down or shake when bumped.

[0010] Compared with the prior art, the present invention has the following significant effects:

[0011] The portable static penetration device has a fixed foot welded at the rear end of the trolley which can be accurately inserted into the opening at the lower end of the static penetration device to ensure that it can play a supporting role during the advancement; the support platform welded at the cross bar of the trolley can support and fix the top of the static penetration machine to protect the chain from lateral pressure; fixed ribs are added to the cross bar to fix the upper end of the static penetration device to prevent it from sliding or shaking due to bumps, thereby reducing safety risks during transportation, reducing transportation time, and improving transportation efficiency.
