Field surveying device for construction engineering cost

Abstract

The utility model relates to an on-site surveying device for construction engineering cost, which is applied to the technical field of surveying devices, and realizes that when depth measurement needs to be carried out on a groove of a construction site independently, a hook plate on a clamping sleeve is clamped into the bottom of a clamping plate to abut against the clamping plate, and then the clamping plate is sleeved with the clamping sleeve by rotating a clamping hook, so that the depth of the groove is measured independently. The clamping block is inserted into the clamping groove and is automatically closed through the self-locking switch, so that the hook plate is fixed, then the extension rods are spliced according to the depth to be measured, the extension rods are sequentially connected in a threaded mode and fixed to the bottom of the measuring rod in a threaded mode, then the clamping hoop is arranged on the threaded rod in a sleeving mode and fixed to the threaded rod in a threaded mode, and then the tape shell on the tape is plugged into the clamping sleeve. When the measuring tape is used, resistance is increased through contact with the non-slip mat, the measuring tape can be fixed in the clamping sleeve, at the moment, the measuring tape penetrates out of the clamping opening and is kept perpendicular to the hook plate, at the moment, the extension rod is placed in the groove for measurement, and the effect that one person can rapidly complete depth measurement on the groove and similar holes is effectively achieved.

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the measuring ruler currently used for construction engineering cost is not convenient for single-person operation, cannot measure the excavation depth of the slope groove, and is prone to measurement errors.

[0006] In order to solve the above problems, the utility model provides a field survey device for construction engineering cost, including a measuring rod, a threaded rod with a handle fixedly connected to the top of the measuring rod, a clamp threadedly connected to the threaded rod, a clamp fixedly connected to the side wall of the clamp, a bayonet opening drilled on the bottom side wall of the clamp, a scale shell with a measuring tape wound inside is detachably connected to the clamp, and the measuring tape is engaged with the bayonet opening, a pull rope is fixedly connected to the side wall of the scale shell, a hook plate is rotatably connected to the bottom end of the measuring tape, a hook plate is rotatably connected to the end of the hook plate away from the measuring tape, a clamp block is fixedly connected to the end of the hook away from the connecting plate, a clamping groove corresponding to the clamping block is drilled on the hook plate, a self-locking switch is installed in the clamping groove, and the clamping block is engaged with the clamping groove, an extension rod is threadedly connected to the bottom end of the measuring rod, a clamping plate is fixedly connected to the bottom side wall of the extension rod, and the hook plate is engaged with the clamping plate.

[0007] In the above surveying device, it is effectively achieved that one person can quickly complete the depth measurement of trenches and similar holes alone.

[0008] As a further improvement of the present application, the extension rod is designed as a hollow ring, and the bottom end of the extension rod is threadedly connected to the top end of the adjacent extension rod through a threaded shaft.

[0009] As a further improvement of the present application, a clamping ring is sleeved on the surface of the threaded rod, and the clamping hoop is sleeved on the threaded rod above the clamping ring, and the surface of the threaded rod above the clamping hoop is threadedly connected to a limiting ring.

[0010] As a further improvement of the present application, the hook plate is fixedly connected to a group of connecting plates away from each other, a rotating shaft is rotatably connected between the two connecting plates, and the hook is fixedly connected to the side wall of the rotating shaft.

[0011] As another improvement of the present application, holes are drilled on the hook plate, and steel nails are inserted into the holes.

[0012] As another improved supplement of the present application, a connecting block is fixedly connected to the bottom end of the measuring tape, and the connecting block is rotatably connected to the side end of the hook plate through a connecting shaft.

At this time, the depth to be measured is roughly judged to splice the extension rod, the extension rods are threaded in sequence, and then the top extension rod is fixed to the bottom thread of the measuring rod, and then the clamp is sleeved on the threaded rod and threaded to it, thereby fixing the sleeve, and then the ruler shell on the tape measure is inserted into the sleeve, and the resistance is increased by contact with the anti-slip pad, so that it can be fixed in the sleeve, and then the pull rope is exposed to facilitate the sleeve to be pulled out later, and then the tape measure is passed through the bayonet and kept vertical to the hook plate. At this time, the extension rod is placed in the groove to be measured to measure the depth, which effectively achieves the effect of being able to quickly complete the depth measurement of grooves and similar holes alone.
