Abstract
The utility model relates to a special safety appliance which guarantees life safety of underground workers in the process of manual hole-digging cast-in-place pile construction, in particular to a safety protective cover. The safety protective cover comprises a support frame and a protective cover plate arranged on the support frame. The protective cover plate comprises a first protective cover and a second protective cover, wherein the first protective cover is connected with the second protective cover through a movable connecting part, and the first protective cover or the second protective cover can be opened and closed through the movable connecting part. The safety protective cover is easy to manufacture, low in cost and capable of effectively avoiding personal injury caused by falling objects in the process of manual hole-digging pile construction, and therefore an expectant safety protective target is achieved.
Description
Technical field
The utility model relates to a kind of special protection apparatus of guaranteeing the underground operators life security in the construction of manual-excavation cast-in-place pile process, especially relates to a kind of safty shield.
Background technology
Hand excavated pile is modal a kind of foundation structure type, and its degree of depth is determined shallow only have several meters according to geological conditions, and dark reaches tens of meters.According to geological condition, generally can adopt concrete or steel retaining wall that supporting is carried out in the well stake, prevent cave-in accident.It but is without the reliable precautionary measures that but object hits, the reason such as hand excavated pile invar rope when muck removal breaks, hoist engine brake failure, manual operation are improper, the lifting thing casualty accident that drops often occurs, particularly (the general degree of depth is 30～40m) to the cutting depth of water conservancy and hydropower vertical shaft pilot tunnel, and potential safety hazard is just larger so deeply.
The utility model content
For the shortcoming of prior art, the utility model provides a kind of safty shield.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of safty shield, the protective cover plate that comprises bracing frame and be arranged at bracing frame top, described protective cover plate comprises the first protecting cover, the second protecting cover, and the first protecting cover is connected by active connection with the second protecting cover, and the first protecting cover or the second protecting cover are opened and closed by active connection.
Further, described protective cover plate also comprises an outer ring, and the outer ring is arranged at the periphery of described the first protecting cover and the second protecting cover formation.
As improvement, described protective cover plate is cone-shaped, and its opening direction is towards workman's construction direction.Because hand excavated pile excavation size is less, so protective cover is made into cone-shaped, so both be beneficial to the stable of device, increase again it and born the ability of weight, and be beneficial to well interior daylighting and ventilation, ensured construction workman's safety and health.
Preferably, described active connection is hinge, draws materials conveniently, makes simply reliable operation.
Alternatively, described the first protecting cover is fixed cap, and the second protecting cover is removable cover, and described the second protecting cover is connected with stay cord, and the second protecting cover is realized opening and closing by the pulling of stay cord.
Preferably, described the first protecting cover and/or the second protecting cover are steel plate.
Preferably, support frame as described above is means for supporting reinforcement steel bar.Means for supporting reinforcement steel bar has certain intensity, rigidity and bearing capacity, ensures for stranded workman provides the time of security protection and enforcement rescue.
Compared with prior art, the beneficial effects of the utility model are:
The utility model safty shield is simple in structure; the protective cover plate that comprises bracing frame and be arranged at bracing frame top; its protective cover plate comprises the first protecting cover, the second protecting cover; the first protecting cover is connected by active connection with the second protecting cover; the first protecting cover or the second protecting cover are opened and are closed by active connection; this safty shield handling ease and cost are low, can effectively avoid the junk in the manual digging pile construction process to hurt sb.'s feelings, and can reach the safeguard protection target of expection.

The specific embodiment
Below in conjunction with the Concrete facts mode the utility model is further described.
Be the embodiment of the utility model safty shield as shown in Figure 1 to Figure 3, the protective cover plate 20 that comprises bracing frame 10 and be arranged at bracing frame 10 tops, protective cover plate comprises the first protecting cover, the second protecting cover, the first protecting cover is connected by active connection 203 with the second protecting cover, and the first protecting cover or the second protecting cover are opened and closed by active connection 203.Wherein, active connection 203 is hinge; The first protecting cover and the second protecting cover are steel plate; Bracing frame 10 is means for supporting reinforcement steel bar; Protective cover plate 20 also comprises an outer ring 204, and outer ring 204 is arranged at the periphery of the first protecting cover and the second protecting cover formation.The bracing frame of the present embodiment is channel-section steel.
Stability and weight capacity in order to increase device are made into cone-shaped with protective cover plate 20, and its opening direction is towards workman's construction direction.Because hand excavated pile excavation size is less, so protective cover is made into cone-shaped, so both be beneficial to the stable of device, increase again it and born the ability of weight, and be beneficial to well interior daylighting and ventilation, ensured construction workman's safety and health.
In the present embodiment, the first protecting cover is that fixed cap 201, the second protecting covers are that removable cover 202, the second protecting covers are connected with the pulling of stay cord 2, the second protecting covers by stay cord 2 and realize opening and closing.
During actual the use, the operating procedure of this safty shield is as follows:
1, blows out and by steel cable 1 protective cover is hung in the shaft bottom with hoist engine after smoke evacuation finishes;
2, adjust protective cover after operating personnel put in place, removable cover 202 is pulled open and fix stay cord 3, in the present embodiment, stay cord 3 is connected by pulley 6 with stay cord 2;
3, hanging basket 4(quarrel bucket) hung in the well by hoist engine, in the decline by the downhole operations personnel by lower stay cord 5 control hanging basket 4(quarrel buckets) descent direction, in case bump against the borehole wall;
4, filling quarrel notifies aboveground personnel to begin lifting with Walkie talkie afterwards, when hanging basket 4 exceeds protective cover plate 20 and does not hinder stay cord, the downhole operations personnel unclamp stay cord 3 and close removable cover 202, if removable cover 202 is difficult for closing and can thereunder fastens counter the drawing of rope and close;
5, the lifting in also available lower stay cord 5 rectify a deviation;
6, unload the complete aboveground operating personnel of quarrel and notify the personnel in the pit to open removable cover 202 with Walkie talkie, enter next circulation.
This safty shield is simple in structure; the protective cover plate 20 that comprises bracing frame 10 and be arranged at bracing frame 10 tops; its protective cover plate 20 comprises the first protecting cover, the second protecting cover; the first protecting cover is connected by active connection 203 with the second protecting cover; the first protecting cover or the second protecting cover are opened and are closed by active connection 202; this safty shield handling ease and cost are low, can effectively avoid the junk in the manual digging pile construction process to hurt sb.'s feelings, and can reach the safeguard protection target of expection.
