[0023] In view of the problems existing in the prior art, the utility model provides a shielding and protective device for blasting construction, which can be stably fixed on the ground when someone enters, and can be conveniently moved under human drive when no one enters, thus effectively solving the problem that the existing blasting shelters are inconvenient to move short distances in the mine site.

[0024] See also Figure 1-Figure 7 The utility model mainly comprises a pedal-brake type mobile chassis and a cannon shelter 1 installed on the pedal-brake type mobile chassis.

[0025] The blast shelter 1 includes a shed body 101 and a safety door 102. The safety door 102 is rotatably connected to the outside of the door of the shed body 101, and a door lock is installed on the safety door 102. The shed body 101 is made of 12mm steel plate, and the outside of the shed body 101 is affixed with a safety sign, painted with eye-catching red paint to represent major risk protective equipment. The safety door 102 of the blast shelter 1 is an outward swing door, which will not occupy the internal space of the shed body 101 when opening and closing, so as to facilitate the entry and exit of personnel. Observation holes 1011 are provided on the safety door 102 and the shed body 101, and high-strength explosion-proof glass is provided inside the observation hole 1011. The setting of the observation hole 1011 facilitates the personnel in the shed to observe the blasting situation. A lifting ring 1012 is provided on the top of the shed body 101, so as to facilitate the long-distance transportation and transshipment of the shed body by large equipment (such as cranes, excavators, etc.).

[0026] The pedal brake type mobile chassis includes a load-bearing chassis 2 and a mobile wheel group 3. The load-bearing chassis 2 includes a bottom plate 201 and a pedal brake mechanism. The pedal brake mechanism includes a pedal linkage plate 202, a control block 203 and an unlocking top spring 2021. The bottom of the side wall of the shed 101 is fixedly connected to the four sides of the bottom plate 201.

[0027] The pedal linkage plate 202 is horizontally placed above the base plate 201. Vertical guide columns 2024 are provided at the bottom of the four corners of the pedal linkage plate 202. Guide blind holes corresponding to each guide column 2024 are provided on the upper part of the base plate 201. An unlocking top spring 2021 is provided in each guide blind hole. The guide column 2024 is inserted into the corresponding guide blind hole and pressed on the unlocking top spring 2021.

[0028] The movable wheel group 3 includes four movable wheels 301 and two mutually parallel rotating shafts 302. The two rotating shafts 302 are rotatably connected to the two ends of the base plate 201. A movable wheel 301 is fixed at both ends of each rotating shaft 302. When the blast shelter 1 is pushed manually, the movable wheels 301 and the rotating shafts 302 rotate at the same time, and the entire blasting construction shielding protection device can be moved on the ground, thereby realizing the position adjustment of the protection device.

[0029] The control block 203 is located in the groove at the top of the base plate 201. A slider 2032 is provided at the bottom of the control block 203, and the cross-sectional shape of the slider 2032 is T-shaped. A T-shaped slide groove 2011 parallel to the rotating shaft 302 is provided at the bottom of the groove at the top of the base plate 201. The slider 2032 is inserted into the inside of the slide groove 2011 and is slidably connected to the slide groove 2011. When in use, the slide groove 2011 can limit the moving trajectory of the control block 203 through the slider 2032, so that the control block 203 will not be skewed, twisted, or rotated when moving, which will cause the device to get stuck and fail, thereby improving the reliability of the device.

[0030] A locking gear 3021 is provided on the outside of the rotating shaft 302, and internal gears 2033 matching the locking gear 3021 on the outside of the rotating shaft 302 are provided at both ends of the control block 203. When the control block 203 slides along the slide groove 2011, the locking gear 3021 and the internal gear 2033 change from a meshing state to a disengaged state, or from a disengaged state to a meshing state.

[0031] A vertical ear plate 2023 parallel to the rotating shaft 302 is provided at the bottom of the pedal linkage plate 202, and an inclined long hole 2022 is provided on the ear plate 2023. A control rod 2031 is provided in the middle of the control block 203, and the control rod 2031 is slidably inserted into the inside of the long hole 2022. When there is no personnel remaining inside the shed body 101, under the action of the unlocking top spring 2021, the pedal linkage plate 202 is always in a lifted state. At this time, under the positioning effect of the long hole 2022 on the control rod 2031, the locking gear 3021 is in a state of being out of the internal gear 2033, and the rotating shaft 302 can rotate freely. When the artillery shelter 1 is pushed, the artillery shelter 1 can realize a short-distance movement through the rotation of the moving wheel 301, thereby realizing the adjustment of the position of the artillery shelter.

[0032] When a person enters the interior of the artillery shelter 1, the person will stand on the pedal linkage plate 202. Under the action of the person's weight, the pedal linkage plate 202 moves downward and compresses the unlocking top spring 2021. At this time, the long hole 2022 drives the control block 203 to move through the control rod 2031, so that the locking gear 3021 engages with the internal gear 2033, and the moving wheel 301 and the rotating shaft 302 cannot rotate. The moving wheel group 3 is locked, and the artillery shelter 1 cannot move, thereby ensuring the stability of the artillery shelter 1.

[0033] The utility model uses the blast shelter to protect blasters or observers. After the blasters or observers enter the blast shelter, the moving wheel group is automatically locked to prevent the blast shelter from accidental movement, thereby ensuring the stability of the protection device. After the blasters or observers walk out of the blast shelter, the moving wheel group is automatically unlocked, and the blast shelter can be moved a short distance in the field under human power, which is convenient for adjusting the use position. The protection device is convenient and flexible to use, and has strong adaptability and practicality.
