Including the skip, to the smooth coal groove of skip dress material, transport the cargo airplane of material to smooth coal groove, its characterized in that: the check weighing board was installed to one side in the material mouth was advanced in swift current coal groove, check weighing board upper end articulates on smooth coal groove, and check weighing board lower extreme is to swift current coal groove centrally -inclined, it is equipped with weighing sensor to keep away from at the check weighing board between smooth coal groove center one side and the swift current coal cell wall. The utility model discloses the quasi -complement old mine do not consider the design bug that skip basis weight loaded because of the shaft building initial stage, solved the unable normal use's of masuring bucket technological problem, avoided the skip to appear in loading process, great improvement vertical skip hoisting factor of safety.
Description
Technical field
This utility model relates to a kind of weighing-appliance, specifically a kind of check weighing board-like main shaft skip weight-fixed loading device.
Background technology
According to " safety regulations in coal mine " the 382nd article of regulation: " skip hoisting must use definite weight ".At present New Built Mine achieves main shaft skip weight-fixed loading substantially, and numerous old mine does not consider to use at the shaft building initial stage and determine refitting and puts and carry out skip loading, but directly employing coal drop is loaded.The loading chamber of such old mine is the narrowest and small, if using the definite weight mode of the newest mine, it is necessary to extending original loading chamber, break the borehole wall, install new equipment etc., workload is big especially, has a strong impact on the normal production of mine.When having part mine to use measure hopper to carry out skip loading, due to actual effects not having definite weight of factors such as raw coal viscosity are big, water content is big, centre deviation is big, measure hopper performs practically no function simultaneously.
Summary of the invention
For above-mentioned technical problem, this utility model provides a kind of check weighing board-like main shaft skip weight-fixed loading device.
This utility model is achieved through the following technical solutions: a kind of check weighing board-like main shaft skip weight-fixed loading device, including skip bucket, to the coal drop of skip bucket dress material, transports the transporter of material to coal drop；It is characterized in that: in described coal drop enters material mouth, side is provided with check weighing plate；Described check weighing plate upper end thereof is on coal drop, and check weighing plate lower end is centroclinal to coal drop；It is provided with LOAD CELLS away between coal drop center one side and coal drop wall at check weighing plate.
It is further: described LOAD CELLS connects integrator of weighing, and integrator of weighing connects a display；Being provided with an auxiliary reclay in described integrator of weighing, auxiliary reclay controls connection transportation machine.
Described check weighing plate includes the weight-bearing surface tilted；It is provided with L-type strut in weight-bearing surface the north；Described LOAD CELLS is between L-type strut and coal drop wall.
Described transporter is belt conveyer.
During work, raw coal material is under the effect of belt conveyer, raw coal conveying is carried out in coal drop, through water conservancy diversion, raw coal material impact is on check weighing plate and produce direct impulsive force, and this impulsive force makes check weighing plate produce a horizontal displacement, is installed on after the LOAD CELLS at check weighing plate rear detects this skew and is converted into the signal of telecommunication, the signal of telecommunication, after integrator of weighing processes, shows flow and total accumulation.When integrator of weighing detects that the raw coal cumulant by this device reaches skip loading specified tonnage, in integrator of weighing, auxiliary reclay sends a switching value, and belt conveyer is automatically stopped operation, loads complete, and skip hoisting runs.During it addition, the check weighing plate of this device designs, only allowing it to move in the horizontal direction, this means that the horizontal component only detecting the total impulse force of raw coal, and have ignored component straight down；When thus can guarantee that solid accumulation or adhere to check weighing plate, the change of produced weight does not interferes with zero point or the degree of accuracy of system.This utility model sufficiently make use of original small-sized coal bunker, coal drop or discarded quantitative bucket body, installs check weighing plate therein, successfully solves such skip bucket and cannot realize the technical barrier of definite weight.
Good effect of the present utility model is:
1, quasi-complement old mine does not accounts for the design defect of skip bucket definite weight because of the shaft building initial stage, meets old mine skip hoisting and uses the requirement of definite weight, is greatly improved vertical shaft skip and promotes safety coefficient.
2, changing existing numerous mines and use the pattern of quantitative bucket type skip bucket definite weight, solve the technical barrier that measure hopper cannot normally use, the application to this art has carried out strong widening.
3, the application of check weighing board-like main shaft skip weight-fixed loading device, it is to avoid overload that skip bucket occurs in loading process, the phenomenon such as underload, protects main hoist safe operation, improves production efficiency.

Detailed description of the invention
The following is a specific embodiment of the present utility model, in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1, a kind of check weighing board-like main shaft skip weight-fixed loading device, including the lifting skip bucket 7 being arranged in main shaft, skip bucket 7 side is provided with the coal drop 5 for filling raw coal material 2 to skip bucket 7, and coal drop 5 side is provided with the transporter 1 for transporting raw coal material 2 to coal drop 5；Coal drop 5 top is a cylinder, and coal drop 5 bottom to lopsidedness and is provided with outlet；It is provided with check weighing plate 3 in coal drop 5 upper port, check weighing plate 3 includes the weight-bearing surface 3-1 tilted, weight-bearing surface 3-1 upper end thereof is in coal drop 5 upper port side, weight-bearing surface 3-1 lower end is centroclinal to coal drop 5, raw coal material on transporter 1 falls at weight-bearing surface 3-1 front surface through deflector, to mono-impulsive force of weight-bearing surface 3-1, weight-bearing surface 3-1 is made to swing along pin joint；Being fixed with L-type strut 3-2 after weight-bearing surface 3-1, LOAD CELLS 4 is between L-type strut 3-2 and coal drop 5 wall, for detecting the displacement of L-type strut 3-2；LOAD CELLS 4 connects integrator 6 of weighing, integrator 6 of weighing connects a display, weighing after integrator 6 receives the displacement that LOAD CELLS 4 is passed to and be converted into the signal of telecommunication, the signal of telecommunication, after integrator of weighing processes, shows flow and total accumulation；Weigh and be provided with an auxiliary reclay in integrator 6, auxiliary reclay controls connection transportation machine 1, when integrator of weighing detects that the raw coal accumulation of material amount by this device reaches skip loading specified tonnage, auxiliary reclay in integrator of weighing sends a switching value, belt conveyer is automatically stopped operation, loading complete, skip hoisting runs.
