Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other elements or other ingredients.
As shown in Figure 1, instrument visited by a kind of pricker according to the specific embodiment of the invention, and it comprises: pricker pin (not shown) and hammering assembly 1.This pricker is visited instrument and be may be used for the spy of building foundation pit pricker, makes the lower end of pricker pin stretch into underground implement operation by hammering.The upper surface of pricker pin is plane.Hammering assembly 1 comprises the axis of guide 11, limiting section 12, positioning sleeve 13 and weight 14.The rigid long axis of the axis of guide 11 for extending longitudinally, its can for along its in axial sliding weight 14 guiding is provided, avoid hammering direction to tilt.Limiting section 12 is arranged on the upper end of the axis of guide 11, and self-steering axle 11 radial direction is protruded, and prevents weight 14 from deviating from from the upper end of the axis of guide 11.Positioning sleeve 13 is fixedly connected on the lower end of the axis of guide 11, and positioning sleeve 13 can be socketed in the upper end of pricker pin, and positioning sleeve 13 is plane with the contact surface of pricker pin and the end face of positioning sleeve 13.Positioning sleeve 13 1 aspect can prevent weight 14 from dropping from the lower end of the axis of guide 11, on the other hand to the pricker pin location of being inserted in wherein.
As shown in Figure 2, through hole is offered according in the middle of the weight 14 of above-mentioned embodiment, weight 14 to be set on the axis of guide 11 by this through hole and can to move up and down along the axis of the axis of guide 11, the internal diameter of weight 14 is less than the diameter of limiting section 12 and positioning sleeve 13, the upper end of weight 14 is provided with the first boss 141, it is handle portion 143 that lower end is provided with between the second boss 142, first boss 141 and the second boss 142, and the lower surface of the second boss 142 is plane.Operating personnel hold handle portion 143 move up and down weight 14 time, the design of the first boss 141 and the second boss 142 can prevent weight 14 from the slippage of operating personnel's hand.Alternatively, weight 14 can be processed by common A3 steel plate.
According to one or more embodiments of the present invention, the cross section of the axis of guide 11 can be circular, and surface is smoothly processed, is easy to weight 14 and slides along the axis of guide 11.Preferably, the axis of guide can be round steel.Preferably, in an embodiment of the invention, the diameter of the axis of guide is 14mm, and the length of the axis of guide is 300mm.Further, the internal diameter of weight is 16mm, and the external diameter of handle portion is 24mm, and the external diameter of the first boss and the second boss is 40mm.
According to one or more embodiments of the present invention, limiting section is nut.
When carrying out pricker to foundation ditch and visiting, the positioning sleeve 13 that instrument visited by pricker of the present invention is enclosed within pricker pin upper end, the two plane contact, and the axis of guide 11 is basically perpendicular to ground with the axis of pricker pin.Operating personnel one hand steered pricker pin, another holds the handle portion 143 of weight 14.During hammering, the second boss 142 of weight 14 is hammered onto the end face of positioning sleeve 13, and the two is also plane contact, and hammer force is delivered on pricker pin by positioning sleeve 13, and the effect that pricker pin is subject to downward hammer force enters underground.Operating personnel hold handle portion 143 makes weight 14 pump along the axis of guide 11, realizes the one man operation that instrument visited by pricker, improve working security, and force direction is stablized, thus improve the accuracy of pricker spy.Further, if the sinkage etc. of the hammer number of binding operation personnel and strength and pricker pin, the situation of bearing capacity of foundation soil and geologic structure can be determined.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
